- In this video the guys will show you how to replace the fuel pump in a 1999 Chevrolet Suburban 1500. Although this procedure was done on a 1999 Chevy Suburban the process will be similar on any vehicle with an in tank fuel pump.
I just replaces mine on a 01 suburban.Jacked up the rear blocked it with tire stands. Tank was half full of gas was not a problem. Used the floor jack to support the tank. Lowered it down towards back of sub and was able to get to pump and replace. Took me 2 hours.
I checked my 1999 fuel pump and it made that unique sound. I replaced the fuel pump relay sensor, air filter and gas filter. Before cranking it up, I pour a bottle of fuel injector cleaner in the gas tank. I tried starting it one time but no luck. So I sprayed starter fluid in the plastic container that's attached to the top of the injectors. My Truck started I drove for an hour and parked but continued to keep the engine on. I drove and parked for almost 4 hours. Happy to say no fuel pump was needed. If it wasn't for this video I would have cave in and followed my no longer mechanic advice. Thanks for the heads up. From me and my Heavy Chevy a.k.a the CHAMP..
I've got a 1999 Chevy suburban and I appreciate your help guys 😊
We installed a new fuel pump on our 1999 GMC Suburban 5.7L L31 CSPI engine with 203,000 miles and it has vapor lock. According to our sisters friend that did the work...we need a new engine as it will not start. You video filled in a lot of information Thanks!
+William Gallant Vapor lock is caused by heat. It's uncommon in my opinion to get Vapor lock on a fuel injected engine. Why do you think it needs a new engine? - Greg
+Gregory's Garage I agree with you, vapor is caused by heat and hence you have vapor lock. The guy is a certified diesel mechanic, replaced the fuel pump, said he had pressure by gauge, yet the truck refuses to start. He then said vapor lock, and that the spider needs to be replaced or the engine replaced because it has over 200,000 miles. I feel that we can still get more mileage and there is no vapor lock. This all started because the truck began chugging, then it finally quit. I thought it might have been the ignition module. Anyhow the guy told my wife because the fuel pump was so bad that the new pressure caused the spider to fail?
What year is your Suburban?
It's been a year operating with a fuel pump sending unit, and we ended up replacing the SPI with the MPI which works much better. During this year we have been using the trip odometer as the gas gauge moves erratically at all times. When it gets a little warmer than single digits and the ice melts I'll check for a bad ground.
Thanks for the information. I hope it warms up where you're from. It's been a pretty warm winter for us. -Greg
Great service guys one of the best I ever watched just one question I didn't see. How did you unplug the snap on horses to the pump?
If you're going to replace the pump anyway then breaking the fittings makes it a little easier to remove.
Thanks
Greg
Great videos. Love my truck and these really help me keep it going. Thanks!
Jeff Goold Thanks for the good words..-Greg
Thanks for the video may have just saved me a hundred bucks worth of labor,
+Daniel Harrell You're very welcome.. - Greg
At least! I had to have a shop replace the fuel pump on my other 99 Suburban several years ago. It cost over $800. Today my neighbor and I fixed my Burb and it cost less than $200 in parts and new tools.
There could be a few different things wrong but most likely it's a problem with the sending unit. Bad thing is the sending unit is part of the fuel pump and to fix it you will have to replace the pump. You could check for good connections to the fuel pump but this will involve lowing the tank to where you can access the top of it.
Greg
We choose to show how to disconnect the lines once we had the tank removed. It was almost impossible to show us disconnecting the lines while the tank was still connected as there wasn't enough room. We also showed the tool we used and how we had to modify it. I believe the way we did it was more helpful since we could show a better view of the lines.
Greg
Fuel pressure regulator
You can also whittle on the partition between the two line barbs on the pump, I did that and it worked.
Excellent video, it'll help a lot when I dive into my fuel pump change.
Awesome. Good luck
You're very welcome. So glad it helped.
Where are you located
What was the problems/ symptoms why they had to change the connector pigtail on the fuel pump
The new connector is mandatory even if the old one fits. GM has a tech bulletin that says many of the dead pumps were caused by high resistance and failing connectors. Many pumps that were installed without a new connector have the new pump fail in three weeks to one year. And you must replace the inline fuel filter or the warranty on the pump is void.
Thank you for the information.
Greg
Greg Cook The Technical Bulletin is #04-06-04-088C Aug 24 2006 and can easily be found by Googling. Note that GM only found problems with the square Metri Pack 150 connector. - Not the GT 280 connector. The GT280 connector is the one currently used on replacements - Delphi and ACD for sure. Nevertheless, since its CLEAR the pump draws lots of amps before it croaks, IMHO, replacing an old GT280 with a new one is a lot easier than dropping the tank again in a year for another dead pump.
I am not so sure the Metri Pack connector was so bad, but GM did not anticipate that users would (1) NOT change the fuel filter ever and (2) run the pump dry; which causes the pump to draw more amps fighting against crap in the old filter. The connector burns/arcs from the amps - raising resistance in the circuit and then the resistance causes the pump to die. In other words, the GT280 connector seems to do a better job of handing higher than designed for amps.
Let me make one last pitch for fuel filters. I have seen 88-2003 GM trucks and burbs goes 150k+ with no fuel pump problems IF the fuel filter is changed every 20k/once a year AND the tank does not go below 1/4 or so. The ACD pro stainless steel filters are only $8 (use new O rings - 84 cents at the dealer). Delphi and Carter now state that install of a new pump or module without a new inline filter instantly voids warranty.
Sorry for the long reply -- I am just perturbed by all the threads that say "I replaced my fuel pump 3 months ago and the crummy pump just died again-GM sucks, Delco sucks, Delphi sucks, etc. etc."
Good video by the way.
Peter Rudy
I'm not debating the need to replace the filter. However, the filter is after the pump. Meaning, the fuel goes through the pump before it goes through the filter on the way to the engine. Why would the filter replacement be tird to voiding the warranty on the pump? The filter doesn't protect the pump as far I can tell.
Stuff it's not that the new fuel filter protects the pump per se, it's that a new filter flows easier and reduces the back pressure on the pump. If the filter has water or crap in it, the pump has to work that much harder, drawing more amps and burning up the pump and connector. Gm uses a very tiny filter for engines that burn lots of fuel. Many techs believe if the tiny $6 filter was replaced every 10k, the pump would last far longer. One mechanic took apart a dozen GM dead pumps. Each had burned up from drawing excessive amps and none had simply wore out.
Wondering why you removed negative battery cable, leaving a vulnerable connection between positive and any till touching body?
By removing the negative cable we are removing the battery connection to the chassis of the vehicle. It would be best to remove both but if you are only going to remove one then remove the negative. -Greg
Auto parts store sold me wrong line fittings.. So I broke the connections like you did in the video... Gas gauge stopped working a month ago so replacing the pump
So I just got a 99 gmc suburban the previous owner had 3 gas lines one feed one return and one on the middle one I’m assuming I should take that out 👀👀👀 also the tank was rusty and leaking so I got a new one but still leaks I never changed one so I assumed that’s how it went but obviously there is no line on the middle so ima take it off maybe that’s causing the leak on the new tank 🤦🏿♂️🤷🏿♂️
How about drilling a hole through the floor to gain access?
Heard some people had done that.
You can do that, but I don't like cutting up the floor. I wish that Chevrolet would have installed an access panel. - Greg
@@GregorysGarage
👍 So do I 😏.
Whats the best way to but the brackets around the fuel tank
Be careful as nothing is holding the tank up. It's just stuck in position. Some gentle prying is probably in order here. Just be careful and make sure it's supported when it breaks loose.
Yes indeed, even less than half full it's heavy! Just did this job on my 99 Suburban 5.7, took all day but we weren't rushing. My neighbor actually did a lot of the work, turns out he just helped his brother in law drop and change on his Burb. I pulled up the transcript and that was very helpful to refer to when needed.
Great vid! Saved me lots of time. Thank you!
Glad we could help. - Greg
Oops I got it you did show lol my apologies guys great work I just did my 99 suburban about to start working on it 👍
No problem. I was just about to respond and saw your second message. Glad we could help - Greg
Have spent 30 min trying to get new pump to seat low enough to get ring on. Im about to just use the old original ring. Im putting 200lbs on the pump and it won't seat.
Got it - I ended up using moly lube grease...
Sorry I am just now replying. It shouldn't be that hard. You will have to push down on it but it shouldn't require that kind of force. Make sure it isn't binding. - Greg
Thanks for the video.
From what I can tell from reading your post, the only things left are the fuel lines and some small hoses attached to the top of the tank. None of this would hold your tank in place. If you have removed the straps the tank should move even with the filler and vent hoses attached. I would probably use a pry bar and try to break it loose.
Greg
So i matched every wire and 3 months later my pump dont woek and the big black wire melted how?
I have a 99 Suburban and I have been unable to put fuel in but like a gallon at a time I checked the Evap line and i can blow air thru them,not sure where I can go from there or if you have a video that addresses this problem. Thanks for any help or advise you can give
Mine is a masterPro Pump for the same Truck with wiring harness: black, Purple, Grey, Orange with black stripe. How do I connect those, and it didn't come with wiring info. Please advise.
Yes the orange and black wire is for the small black wire on the truck. On mine there were two black wires, a larger one and a small one. The larger black wire goes to the larger black wire on the truck. Purple to purple and white, gray to gray. My pump didn't come with these instructions but I got the information from the video and transcript.
Thanks for the tip of modifying the tool, perfect
Awesome video. Thank you
Thank you Greg. That was helpful. I'm replacing mine tomorrow.
I have to have my vehicle towed..
To the shop...let them fix it....
Does you know where the pressure sensor location is for a 1999 Tahoe? Is it on top of the fuel pump or actually on the tank?
Appreciate it!!!!
I’ll tell u wat ion watched of ur new videos but if yall kept this up for 11 years then Inno yall doing it big these days
Make sure you get an ac/delco pump, those aftermarket pumps are trash and won't last. Also make sure to never run your tank below one fourth, because the pump needs to remain submerged in fuel to lubricate and cool it. It'll burn them out faster than jack sprout if you drive on empty in GM vehicles.
havefunbehappy Thank you for the comments. I have used different pumps and have had simlar results with them all.
-Greg
What does it mean if my pump is whining?
George Ramsey lol
like the gm original ac delco ignition switch that has killed 12 people already when gm knew all along it was faulty. i have very little faith in factory parts, most are made by other companies anyway, denso and delphi are as good a pump as you can by. ever since in tank pumps came out most of us knew to keep fuel level above the pump, thats the only way the pump has to be cooled is with the fuel.
Whining is the same thing as complaining!Ya know like, kill me now (Replace) b4 I give up on ya completely
Why did you not show how the new pump with o ring goe in to tank cause it doesnt just drop in
How the heck did you put the new fuel pump in the tank? The o-ring with the my new pump won't fit.
Did you figure it out lol cause I'm having a bitch of a time with mine
@@YeahNoToastTho Oh yeah you pretty much had to throw your weight on it when pushing it in. I had to use bursts of energy pretty much going at it like a wild man. I know the top of the fuel pump was plastic so I don't remember how breakable it was so use caution when appling force. It can be done for sure though. It helps if you put a touch of motor oil around the o-ring. Good luck!
@@wolfzwiful Hey thanks for getting back to me! Yeah we ended up using some heavy duty grease. That was fun lol
Yes motor oil or grease will help with the installation of the O ring and pump.
I have a 99 suburban and the mechanic says it has that problem and charging me 700 buck to change all that. Is that a ok deal or he's over charging me? Thanks But I don't know nothing about cars and prices
I know $700 is a lot of money at least for me. But it doesn't sound unreasonable for replacing the fuel pump. The fuel pump will probably cost around $300 by itself and then you add labor. I hope this helps. -Greg
Way to much. Always buy parts from parts store they come with a warranty so you only have to pay for labor.
My mechanic only charges $300 for the part and labor combined.
You skipped the positive side alternator check. I can figure that out easy enough but what voltages should I look for?
really great vid want to know how long did it actually take &the the fuel pump on a chevy silverado is not the same mine is just a little bottle culd it be just bought the parts today
It takes around 2 hours or so if you have help and depends on how much fuel you have in the tank. Not sure about the Silverado but it should be similar. Mine went out with out one time with over 30 gallons. -Greg
you bought the pump only, he replaced the entire module, more expensive but you also get all new parts and most likely updated equipment, now you have to pull the module out of tank the same way as in this video, you will be able to see the pump inside , just replace it,
I'm hoping it's just the Fuel Pump Relay that's causing my '99 Suburban to have a long, and hard start at 1st. crank in the morning, but I'm not sure if it's THAT, the FPR., or the Fuel Pump. I was told, it could most likely be my Fuel Pump, but I had the Fuel Pump changed only 4 yrs. ago, and when it finally does start, it stay running like new, all the way until I, cut it off again...then, it cranks, and starts without a problem...unless I, leave it sitting for a few hrs.. I'm confused..
Yahachazaq Yasharahla did you ever figure out what the problem was w you suburban? I’m having the same issues...
Where did u order this pump?
When I start my suburban occassionally it sounds like a gun shot. I know it needs a new fuel pump. Could that be causing the loud shotgun sound when i start it?
I have never heard a loud noise coming from the fuel pump. I have replaced 3 of them in a Suburban and either you heard the hum or nothing.
-Greg
Do you know what could cause that type of sound?
Crystal Irvin Not from the rear of the vehicle I don't. Where is the sound coming from?
-Greg
Sounds like under the hood
Crystal Irvin I am really not sure what that sound could be but my Suburban would make a clunking sound when cranking. When replacing the head gaskets we noticed that the block was cracked. I hope that isn't your problem.
-Greg
hats the name of the tool you use to remove the lines . 7:18
I have a 2001 gmc yukon. Would this guide be ok to generally follow to replace the fuel pump? Or did they change to much in the intervening years?
I am not 100% sure since I haven't replaced a fuel pump in a 2001 Yukon but I believe it would be similar. -Greg
Sometimes the fuel pump will get louder before it goes out. But that wasn't the case for this one. It just quit. But most if not all fuel pumps make enough noise to be heard.
That's exactly what my Burb did. Filled it up on payday, drove it 95 miles for work that day. Parked it so I could drive my crew cab, and went to move it a couple days later and it would not start. Was cranking fine but not running, because there was no fuel getting to the engine. 214K on the original one, and it just said" OK I'm done"....
I'm replacing the fuel pump on my brothers '97 Suburban. I disconnected the filler neck and vent hose, as well as the electrical connection to the fuel pump. And last but not least, the straps to the tank. I can't drop the tank to gain access to anything else. It is STUCK in place. I noticed that there is foam placed between the frame/sheetmetal, and the tank itself. Is there anything else that the tank is physically attached to? Even putting my upperbody weight on the tank does nothing to loosn
Was the new ele. connector that came with the new pump ness.? Cause I jst changed mine & now my gas guage don't work, but it's the exact same connecter!?
The original design of the electrical connector was a bad design and most new pumps come with a new better designed connector. So if your new pump comes with a new connector then I would suggest replacing it if it's never been replaced before. The new connector should be different from the original one. If yours is the same then your fuel pump may have been replaced before. I would double check all the connections.
Greg
Very helpful. Thank you.
I got a fuel pump from OReilly, and it wouldn't fit into the TAnk: meaning I couldn't get it to compress all the way down so it would fit around the opening. It was too tall. Going with a AC Del co this time and hope it works. Should it be extremely hard to put the new one back in.
Sorry for the late reply I have been having computer issues. But to answer your question, no it shouldn't be hard to put back in. If I remember right you have to apply a little pressure to it. -Greg
Thx Greg we got it in, but is was hard as hell. the truck is running again, I do hope its the right piece.
Thank you
Awesome Video !!! Thank You !!
You are very welcome. -Greg
& I didn't install the new ele. Connector, could that b the problem?
I have seen people do that but I wouldn't recommend it. It's fairly easy to drop the tank. Another option would be to remove the bed. I just don't like cutting holes in my vehicles..
What do you do when after you remove the straps and the tank still won't lower
Sounds like its stuck in place. You will need to break it loose by either bumping it or prying on it. Be careful not to damage the tank. - Greg
I really don't know. I wouldn't think it's your brake light switch or none of the brake lights would work. I use to have problems with mine blowing fuses when I towed my trailer. I had to increase the size of the fuse. But I think all of my brake lights didn't work. I wish I was more help.
Were did u buy that motor oil can from
I am not sure but probably Wal-Mart or Advance Auto. -Greg
How long does it take to replace a fuel pump
I would set aside half a day. You have to drop the tank and depending on how much fuel is in it depends on how easy it is. Dropping a fuel 40 gallon tank isn't fun. -Greg
@@GregorysGarage how much does it usually cost
@@mikerey5605 I just checked the prices at my local O'Reilly's and the pump is between $200 and $300 depending on the one you buy. You will need the line disconnect tool and that is probably $10 or so.-Greg
Yes that's what it took my neighbor and I to do the job. I got a lifetime warranty pump for around $140 because I bought it through a friend's commercial account. Normally would have been $250+.
Great video and help
My gas guage is not working can you give me some advice please
Hey, I have a 98 suburban and when I try to start it, it stalls.. or it’ll act like it’s gonna start then cut off after 2 seconds.. I’m thinking it’s the fuel pump, but I don’t know.. I wanna actually know what’s wrong before I buy a new fuel pump.
Can you hear the fuel pump run when you turn the key on? - Greg
Gregory's Garage yes, if I’m not mistaken.
Gregory's Garage I also read somewhere that it might be a mass flow sensor or something like that.. I’m just trying to not waist money on something I don’t need.
@@kooley_hoe6084 Another yhing is it could be yhe fuel filter. -Greg
Gregory's Garage I changed that already, but what I’m think that it is the mass airflow sensor
Thank you and God bless!
You're very welcome..
-Greg
...it. It just stays tight in place. Doesn't budge. It makes me think that there is something else holding it. Or I just need to get a lot more aggressive in removing it.
My truck hums when I try to start it. It doesn't start though. Could it be the fuel pump has gone bad?
I was driving and my truck cut off. The check gages light is on and so is the battery light. I don't know what either of them mean.
Does the engine turn over when you try to crank it? If the fuel pump is bad the pump doesn't make a noise. When you turn the key to the run position you should be able to hear the pump hum .
@@GregorysGarage yes. It turns over. What we found was that the fuel makes it upfront but it stops there. If you pour gas in the mod (the carburetor looking thing) it cranks but doesn't stay on.
@@kimberlyburdette5511 How do you know fuel is getting to the front?
@@GregorysGarage because he pressed the fuel thing in and gas shot out. I suppose it could be fuel that was already in the line. What do you think it could be?
@@kimberlyburdette5511 Fuel filter?
Or for those of us that want it done quicker, cut an access panel inside and do it without dropping the tank.
I suppose if one's vehicle is a total shitbox then that is an acceptable option. Personally I'm not into doing ghetto work.

Hi guys...
Would you happen to have a video on removing the gas tank on a 92 GMC C1500?
Thank you,
John
John,
I am sorry we don't. But since the body style is the same as the 1999 Suburban this video should be close.
Greg
Thank you for the response Greg...
Suburban tanks are in the back and easy to get out, C1500 tanks are closer to cab and much harder to get to and out. That's why so many people on TH-cam cut access holes in their truck bed or take the bed off altogether.
Thanks so much for your time,
John
John Dumas You are right I don't know what I was thinking.. And that would be a great video. I hate to see someone cut a hole in their bed.
Greg
Yeah... and there is not a single video on TH-cam covering removing the tank and working on the fuel pump, for that series Chevy or GMC truck.
Bummer...
John:)
Hopefully the tank was low on fuel because 40 gallons of gas weighs a whole lot and it takes a while to siphon
Yes it was low this time but once I had it go it with almost a full tank and you're right it isn't fun. -Greg
Modified tool ?
The original tool we had didn't work so we had to shave it down. I think newer tools are sold that will work without modification. -Greg
I undo the strap bolts and the tank won't lower.
The tank is probably stuck. Tap it with a rubber mallet or something similar. -Greg
We removed the reply so we could crank the engine over to relieve any fuel pressure that may have still be in the lines.
Well done
i love this vido
🙏👍🇺🇸
"Dont siphon by mouth". Shows tube with no bulb or suction making device attached....
Awesome
Thanks
+metalfox1911a1 You're welcome. -Greg
i have a 1997 chevy tahoe ls 5,7lr and it macks a huming niose from the back win ti starts and win its off
The humming noise is normal. That's your fuel pump working. That being said. Some fuel pumps get louder before they go out.
Greg
ok thank you sr
What no safety glasses?
We really should of had some on when working around the fuel. Thanks for catching that. -Greg
its your blinker switch on yur truck I just had to replace mine
'99 CHEVY Express, my gas gauge pegs out at 3 o'clock, and van will not start.Mechanic cleaned terminals on PCM and said it should work,,, well it doesn't. New fuel pump,rotor and cap,cam, crank and throttle position sensors. New ignition switch, filler neck ground strap, pump relay. Lost need help desperately.
Rocky Raccon Does the fuel pump turn on?-Greg
yes
It will drive till gas gauge pegs out.
Did you change the fuel pump connector? A lot of the new fuel pumps come with a new connector. The one from the factory was a bad design
Greg Cook Yes.
Rocky Raccon Definitely sounds like an electrical problem. Does the fuel pump shut off once the gas gauge pegs?
I need my fuel pump changed ..
P.S. didn't notice any ground wires on tank.
Rocky Raccon Check gages light comes on also when the gauge pegs.
NICE....Cut the video at 8:59, skip the ACTUAL INSTALL (which is why we watch this video) and go straight to the retaining clip.
Not really sure what you are talking about.. We show the installing the fuel pump. Now we don't show placing the retaining ring down for some reason but we do show putting it in place.
-Greg
How about a pump..
To pump the gas out of the gas tank
Not a bad idea if you can get it to work. - Greg
1999 chevy suburban
Hahahaha! It fell off your stand, didn't it? lol I hate that shit!
+Steve Perley Honestly I don't remember but the tank is so large and bulky it's very easy to do. -Greg
240p wtf lol good video tho
I just brought all my tools home to do this job and forgot snap ring pliers!!!! Why GM Why!?!? Why use a snap ring when everyone else uses a locking ring. God I hate GM
Snap rings can be a pain. I hope everything goes well. - Greg
this is stupid they overkill everything
Thanks for the well-done video. Didn't notice connecting the new fuel pump to a ground on the body ... is there a wire for that? If so, does it connect to the frame outside or inside of the gas tank footprint? I'd like to check the ground if possible before dropping the tank.
Sorry but I no longer have this vehicle. I don't remember it having a separate ground though. I think it was grounded through the connector. -Greg
