Hi Matt. I was thinking if your deleting the Flex fuel maybe remove the Flex fuel sticker on the gas filler door. I watched you video on the brake lines and as I blew a line I was wondering if the parts for your 04 are the same as an 03 Z71 ? I wanna go Stainless brake lines and replace the Flex fuel lines as I've been running on E85 since gas prices went up. Adl question what is your Z71 avg gas MPG ? I Picked my Z71 from my neighbor in Oct 2021 and he's not one to pay attention to MPG's nor am I but the drivers information center says I'm averaging 6.9 to 7.0 MPG on E85 and maybe 3 tenths of a mile more on Super or Reg. I was getting 6.6 MPG till I replaced the Air filter. It seems to run smooth but im dumbfounded to why as it should get around 15-18 I even removed the third row seating to save weight. I'm might get on it on the Expressway but not in town. I believe it only has 94k. I have so many questions for you like how do I find a shop that does HP Tunning here on long Island? Hope you answer. A loyal follower Eddie J. Ps. Install GasBuddy on your phone and you can locate E85 stations and find the best prices on gas or diesel in town or as your driving someplace as the app uses your GPS. Hope that helps.
So you bought the fuel line I would need for my 2003 hoe 😂. Mines only 4.8l 4x4 LS Tahoe 2003 with Bose and 145 amp alt my goal is to keep engine the little guy upgrade radiator, fans first then upgrade transmission, fuel lines , and fuel pump then move on to engine. The hoe only has 286,000 miles with original engine and transmission 😂 she is literally a classic now next year she'll be old enough to drink maybe I'll give her shot fuel additives.
Excellent timing. I have my entire driveline out for a rebuild and was just about to order new factory hard lines. These look like a way better option. Also doing the coil over conversion and e fan upgrade. Thanks for the grest content.
Thanks Matt.. I admit that I was a little reluctant in purchasing the fuel line kit. The owner assured me 💯% that it will work & will hold up under the hood heat temps... So I thank you for your demo installation & part list... Enjoy ✌️🙏
The last time I saw fuel spraying out of the fuel filter fitting I was under a 1989 Dodge Dakota… ended up in the ER having my ear flushed after getting gas in my eyes and ear! Good times! 🤦🏻♂️🤣
Just replaced the whole fuel system minus the tank and tank sensor while replacing the rear main, timing chain cover, and oil pan gasket. I figured replace it while it's all accessible. Go figure the fuel tank pressure sensor failed after the project was completed, and promptly replaced with a bunch of swearing. My Hawkeye is a 05 Tahoe with 262k and just passed emmissions
I just eclipsed 262k today in my 03. Did my oil pump 2 weeks ago. 60lbs going down the freeway and no more lifter tick at idle. Dropping the front diff wasn't as bad as some make it out to be. I've got an electric fan and harness from an 05 ready to go in but my HP Tuners order is on backorder.
@@RYTHMICRIOT Yeah I did the oil pump and oil galley plug that's under the rear main when I had both the timing chain cover and rear main off. A pain if that's the only reason you're there, but easy if you're already there
I'm ordering this for my 07 1500 classic for sure I've been dreading doing that job I live here in New York (chenango county) and even as clean as my truck is for being a ny truck underneath is never fun to work on ever lol
I changed the fuel filter on my Silverado I used to have and the fuel sprayed out like that. I turned my head and got an ear full of gas. Burned like crazy and my ear felt plugged for a few days.
I’m running e85 on my truck with these gas prices she only used on the weekend but with gas at 6.69 in Cali and e85 at 3.69 I think it’s worth it for now.
My 04 Tahoe has that blue style clip on the feed and of course being in Ohio it's the same except it won't come out by pushing the tabs in towards the line and just pull it and the rubber bushing on the line out either. I'm pulling my hair out over it about to just drop the tank and go all new
All vehicles should come with SS brake and fuel lines right from the factory. The few $$$ more at the time of purchase outweigh working on RUSTBELT components later on in years.
Hi Great Vid, and perfect timing for me as well. But if my eyes don't deceive me... The location of your return fuel line is located right below your supply. What year is your vehicle? Mine looks to be a little different than yours. I have a 2005 Yukon Denali 6.0. Was going to attach a picture of mine but it wont let me
I have a gmc Yukon 1999 4x4 with a 5.7l engine in it can I use these lines on my truck and what do I get flex fuel or non flex fuel and all my lines are the original ones witch are rusted and can’t even take off my fuel filter can someone tell me witch ones to get is it flex rule or non flex and would these fit my truck
Yeah I need to do my gas lines on a GMC cut fan 14 ft 1983.. I know it's going to be a beast of a job.. worst case scenario,i will get a new f****** gas tank too maybe too, but the first thing I got to check is the fuel pump I'll put a line on it and see if it's pumping into a little Jerry can gas tank.. I looked at the gas line and it's metal and then it's rubber metal and rubber hose that connects to the inlet, the outlet of the fuel pump goes to the carburetor is metal lying but someone snipped it and put rubber with hose clamps.. so I'm hoping I can just get some 1 inch fuel line or whatever it is half inch
It was strange it was running for like a half an hour idle and perfect then I took a started like just driving it up and back and forth the driveway and then it died and then it won't get no gas in the carburetor so I put a new fuel pump in it and that was a f****** bastard too I had this little push rod in it that kept f****** falling down it took me f****** 6 hours to put that f****** fuel pump in talk about a f****** nightmare I had to make this little thing a wire that I would hook the pin up and then slide the fuel pump in.. took like 20 f****** trys.. but I finally got it thank you Lord
I would love to not pull the transmission out because I have a rock Driveway. Is there any other way to pull the ones in the front without doing that???
I need some help. This is what I "THINK" happened to my 2005 Chevy Tahoe Z71, 4wd. I "THINK" the battery was failing so the computer turned off the Body Control Module to shut down to conserve energy. Things like, windows, door locks, gauges, radio and AC. The driving functions, things like wipers, headlights and cruise control still had power. Finally, there wasn't enough power to restart the engine. I installed a new battery and it started right up and drove 150 miles home, but the BCM systems were still not working. Although, the windows and radio did function whenever they felt like it for a few seconds and then would stop. The alternator was always at 14.1 to 14.8 even on the dying battery. Do's the BCM need to be rebooted after the battery change or a situation like this? Any other thoughts? Anybody?
Hope you read my comment and respond even though the video is 6 months old. I have a '93 GMC 1500 Truck that the fuel lines are leaking on because it was in Iowa for the first 12 years of it's life and the road salt rusted them out. The entire underside is extremely rusty but the body is still good because I had it "Steel Sealed" when I bought it new in '93. OEM steel lines are no longer available and nylon lines are my only affordable option. I can't do the work myself due to my health and have to have an auto repair shop do it for me. Only 1 of the 4 shops I contacted would do it, but it will be a first for them and I am concerned about their ability and speed (they charge $100 per hour labor). I am retired and don't have a lot of money and don't really want to sink any more than necessary in the truck to keep it running. Do you have any advice for me?
There is a fuse in the fuse box under the hood that controls the flex fuel sensor. You need to lift the box up, check the two wires that run to that fuse because it controls the purge valve under the hood as well. Wiggle the wires and make sure it's seated properly. I had that code on my 04 and after digging into the wiring and checking things out, I made sure that connection to that fuse was good and clean and tight and I never had the code come back. The sensor itself does not go bad very often. The only real way to properly check the readings on the sensor are with a GM TECH2 scan tool or an expensive tool truck scanner. Trust me on this, I spent months on my truck with this damn code. The sensor isn't bad. And while the wiring may look okay, it's probably ever so slightly loose.
Interesting you have an external fuel filter on your 04. Must have been flex fuel specific. I know most of the GMT800s went to an internal filter/regulator on the fuel pump assembly on 04. Or more specifically the SUVs
No, the 04 flex and gas both have external filters and regulators. They are different. I had an 04 and did a ton of work to the fuel system. And it was a nightmare ordering the right parts. I believe in 05 they went to a returnless system and the regulator was built in.
@@thagerdorn2009 GM must have made changes at some point in 04. Or it may have varied by model. My 04 Escalade does not have an external fuel filter. I searched high and low for it, but found out my filter is actually part of the fuel pump assembly.
@@ttrmotocross my 04 suburban flex 5.3 had an external filter, and the pump was a plastic housing. However my 04 Sierra gas 5.3 did not have a filter externally and the pump was metal. Somewhere in 04 they went to a return less system. But the flex trucks still had a return system. I believe the L59 Vin Code Z was the flex trucks. 8th digit of the vin tells you what engine it has.
@macaaroni I can absolutely confirm that the filter was deleted/omitted on 05/06 Tahoe without flex fuel. I have an 05 non flex fuel Tahoe. It’s been fun to find all the differences from 02 to 04, then 05 and up. Lots of little things were changed all over these trucks.
@@ManicMender I wonder if those changes were for more profit or to avoid issues since it was the last few years of those trucks. For example, they removed the cabin air filter, which i can't understand at all. I actually got a kit to retro fit one in.
@@ManicMender I have a 04 Tahoe without flex fuel and external filter. It does not have returnline either exept for vapour, so maybe the chang came already sometime i 2004. My VIN nr. is 1GNEK13T64J298248
Please god someone help I have a drive train out of a 89 suburban old Chevy 350 going into a 90 k1500 need fuel likes anyone have a idea where I can get a set?
Don't be like me, just buy the correct fuel lines.. Both parts for flex and non flex fuel are linked in the description!

What is wrong with them? Idont understand should I get this or just normal lines
Gotta say, the untold hero of this story was the Milwaukee flashlight, what a beast
I also installed these lines for my tahoe and bought a set for my dad's 96 burban. Had them for a couple years and so far so good
Excellent timing. I have my entire driveline out for a rebuild and was just about to order new factory hard lines. These look like a way better option. Also doing the coil over conversion and e fan upgrade. Thanks for the grest content.

Love the nylon fuel line. It's all we use at work for replacement. No flairing or bending and the quick connect ends attach easily.

Oklahoma boy, bought a Minnesota truck, fml
I had to replace my fuel lines on my 03 suburban last year....I had trouble finding the flex fuel lines....found the GM ones for $500🙄
Do brake lines next? Just had mine go (05 Yukon 223k miles) and DIYing it was rough.
He did a video on brake lines already, he used preformed lines.
Yep I have a video on the install.
I just did too!

I would love to not pull the transmission out because I have a rock Driveway. Is there any other way to pull the ones in the front without doing that???
