Used a regular 18mm Craftsman wrench. Used the boxed end on the wrench. Tapped on the open end of the wrench with a brass hammer. Tap tap tap until it came loose. Installed plug same way. Tightened by hand as much as I could, then tapped it over a quarter turn with the brass hammer.
Put this on my 07.5 LMM holy crap this made a big difference in how my truck ran!!! It even shifter better!!! I did however crack a rib getting it loose so I believe Sasquatch put mine on! 😂 but I’m good now
I have a cummins 6.7 and had this issue on my truck. Took it to a mechanic here and told him that I don't have power when towing my 5th wheel and check engine light comes on. When driving without my trailer the light disappears after a while and i can go 70-80 mph. Hook up my trailer i can't go faster then 50-60 mph. He counted figurer out what was wrong. After watching this video i decided to pay the $40 with shipping and order this and replace it. Its been 2 weeks now and I'm hauling my trailer with no problem and its running well. Thanks guys.
so my question is i drive my truck daily and mine just did this so i parked it and i believe this is the issue but if i put one without the release valve like yours don't i risk my injectors getting over pressured and blowing up? also does my fuel economy go down because it blocks the extra fuel going back to the tank or does it not block that?
I had a 6.7 Cummins in the shop that ran away on the owner from oil in the intercooler after he replaced his failed turbo. He had installed a rail plug at the same time. Turned key off, Injectors turned off but engine running at 5-6k rpm and no where for the fuel pressure to go. Yeah bad combo, blew the pintle out of the ends of 4 injectors and cracked the tip of the other two nozzles! I install these plugs and believe they are safe 90% of the time but beware that if your truck engine were to run away and the injectors are off they will be destroyed and so will your cylinders. I have seen and heard of lots of engines having run away following turbo failures when the intercooler doesn’t get cleaned/drained/replaced. (Not under my care). Generally they shut back down after a minute or so and the engine survives. Point is in the case of my one customer the factory relief valve would have been the difference between a 60k mile motor living on instead of catastrophic failure.
What are the symptoms when this goes bad? I heard a drop in fuel pressure but then that would mean the injectors aren’t getting enough fuel so I would imagine the motor would sound blown. It’s pressure relief so does it relieve fuel, air or both? Why no oring? I’m thinking just an Oring so why not go with a new oring? .20c part
Yep, used one on my cummins and blew the top off one of my injectors.filled the motor with fuel. I was towing at night and in the rain and never knew it happened until my idiot light was going off and I looked and had no oil pressure. The oil was floating on the fuel and blew out the breather. Good thing, no hydro lock and motor is still ok. Reinstalled stock valve. Be aware. They are there for a reason!
I have an LLY with 8,000 on the motor. No mods except a RDS 64mm turbo. New engine throughout. My issue is that the fuel rail pressure is all over the place and sounds like a blown engine. It started 2 months ago and sounded like an injector knock but got much better when running above 180 degrees. Now it does this all the time. 3 shops have had it and no answers. I don’t recall it even throwing a code at all. Engine still running horrible and can’t drive it. Any advise would be great
Lots of questions about LMLs I have 2015, same problem, but cant find any videos It's on the front of rail drivers side The back port is a sensor, the front is valve I cant find anything on how to get in there, may have to take EGR off
Will having the stock plug on have to do with my ac compressor shutting off I have a early 04 lb7 and I realized every time I step on it my compressor shuts off.
Lb7. Zf 6speed. Is it a more tense scenario? Multiple revs up and abruptly down again at full throttle. In rapid succession. Maybe the sprung version of the plug is more desirable??
I had this code return today P0087 w/Low Power Mode. This happened while towing 9,000# 5th wheel. Fuel filter was changed 2,500 miles ago. TP3018 GM Filter Thoughts?
These parts got me a headache, and my CRDI engine always gets hard starting 4 to 5 cranks before it starts, these tiny parts is very important on common rail diesel engine.
I have hond civic 2.2 cdti trying to get power up hits 220 bhp get low rail presser P0087 Do you do upgrade valve I have all so looked to get fuel pump upgrade but can't find bosch agent that upgrade it Or aftermarket pump Only can find for VW bmw do do pump upgrades?
Hey Guys, I have a 2006 Duramax LBZ motor with a bad fuel issue. I can drive down the road and the engine will just cut off. It’s like the fuel pump loses signal and the engine will just stop running. I put it in park, turn the key off and restart the truck and its like it never happen until it does it again??? Lately I have been getting a 0088 code fuel rail too much pressure code and I will clear it and it goes away for a while, but it resurfaces. Can you let me know what the problem is?? Could it be the sensor in this segment??? I want to know before I have to take it to the dealership and pay an arm and a leg!!! Thanks!!!
not sure if this thread is still active.. I have a 2005 lly engine code "2" my truck will go into limp mode and not let me go above 65.. and damn near nothing with my 5th wheel. New fuel filter. It never throws any codes though?? I was thinking of doing the FPR but maybe this is what I need? or both? truck is completely stock.
My MP8 mack/volvo engine which is a 535hp engine and it is having boost issues, flat out getting to 200kpa then outta the blue it will boost at 260 and runs like a dream,if I stop or slow down it will drop out and go back to 200kpa. Could be the issue
Just had a issue today. Had to get on it hard to get out into traffic. Let off at the next light to turn truck shut off cranks but no start. Basically bone stock 05 LLY changed filter and water sensor now is it possible this is the problem.
I have a Volkswagen Touareg 3.0TDI with a cp4. I occasionally get a p0087 code & the truck starts to surge. It'll smooth out on its own after about 20 seconds or if I tap the throttle. Would this be the relief valve or the regulator valve on the cp4 pump?
I have low fuel rail pressure code when towing. When I come to a red light. It will be in limp mode when I try to get going again. I have a lb7. Help please.
Give us a call, 815-568-7920. Reference any codes. We can help assist in the right direction, but it would be best if we could diagnose the truck ourselves.
I have a 2007 classic 6.6 Duramax Chevy Silverado and I've had this code show up while towing my 25 foot Pro-Line boat will this help and will it damage my stock engine. it had only thrown the code and went into limp mode when pulling the boat up a steep hill or Mountain.
I have a P0088 and my rail pressure bounces. I run a sump to airdog 200 and I replaced the fuel pressure regulator but still has high psi on start up and the drivability is here and there until eot is normal. She also bouces at idle from 5-10k psi on the rail.
It was my pump going out. I fixed it by replacing all my injectors, tubes, and installing a rail plug and 12mm injection pump. She doesnt see below 14psi. I have an inline psi guage before my injection pump and my mm3 shows my rail pressure.
Why does this not apply to lb7? I just had my stock bosch injectors replaced and they said they were going to do this part as well and im pretty sure it shows on my invoice
Im seeing slightly low rail pressure at WOT truck always only makes 21k or a hair more but is demanding more. Has no problem getting to that 21k. Do you think my PPE rail plug not being torqued hard enough could cause this? I was not the one to install. Truck makes the same rail pressure on each tune and still has plenty of power. What gives
I have a stock LBZ engine No tuner. do not have any fuel rail code or pressure codes. Will replacing fuel pressure relief valve do any damage? Will it improve drivability?
We've installed thousands of these fuel pressure relief valves without any issues. It may improve your truck's driveability if you're experiencing problems now.
Will this solve a p0191 code? I got perfect fuel pressure on my scan tool. Does this work with the LML rails? I had this code before I did the cp3 conversion and a fass lift pump. My cp4 didn’t have any metal and never had an issue with it. I only didn’t the cp3 conversion for a peace of mind.
Lb7 has no rail pressure relief valve. Check air filter, check for boost leaks, check your turbo wastegate, if all are good, check your injector balance rates. You'll find your answer fairly quick.
Hie guys i have a problem wth my common rail mazda b2500. It does not start on its own beside using quick start. And when it start it idles but upon acceleration it switches off. The code am having is p0607 plz anyone who can help.
I have a 2006 LBZ Duramax I have idle issue when I put it in reverse or drive or AC on it runs good but if I put it in park it idles up and down could this be the problem?
I have a 2011 duramax 6.6 that is having these issues but looking at the end of my fuel rail on driverside I see a electrical connector. So any advice?
I know this is an older video, but I did this fuel rail plug. And than I bought a ppe ported fuel rail fitting. And that ported fuel rail fitting leaked fuel like crazy(while I was on a trip with my fifth wheel camper). Luckily i swapped my stock fitting back in, but I’ll still get that low rail pressure code if I horse on a high tune. Did I do something wrong or should i drill my stock one out(ppe fitting has 3 or 4 threads showing)
Thanks for the info. Are you going to to a video on The 2011-2016 LML Exergy Fuel pressure regulator? Also what’s your thought on that as far as is it worth it if the CP4 lets go , will it help? Thanks
Right on. Thanks. I really like how on your videos you guys come across like, here's the do's and don't and that's that. You don't over sell your products. That's a huge mistake with the other companies out there. I'll be ordering product come spring. It's just too dam cold here in mn. Thanks.

I have an 06 3500. I get a ticking noise for a couple seconds then truck blows white smoke then it goes away. Could this relief valve cause this to happen if it's bad
There are a few things that can cause those symptoms. A new fuel pressure relief valve is a good idea, for starters. Can you call us so we can help you kick around a few other ideas? 815-568-7920.
What could cause similar issues to this on a LB7? Got my LB7 tuned and it ran great for 2 weeks, now it keeps throwing a P1093 code and the fuel pressure drops significantly WOT. The second I let off the throttle the fuel pressure jumps up to where it should be. When I give it half throttle it runs as it should
Is the relief valve an issue with LML models, I'm getting ready to do a full delete and I don't want to create any issues with the added power. Granted I'm guessing around 200 horse and 400 lbs of torque increase, but like everyone else I'm looking for better economy and reliability as well.
This DOES NOT apply to an LB7. There is no fuel pressure relief valve on an LB7. For the Duramax trucks that have the relief valve, I saw 74 ft. lbs. somewhere for this little guy! Just crank it on there like the good men at Calibrated Performance said to.
Today I got the p0087 while towing and forcing the truck abit uphill and truck went into limp mode, is there any risk on replacing stock valve with this? I drive a 2012 ram 3500 6.7 full stock.
Daniel had the same exact thing with mine. 2011 ram 3500 after I deleted! Had p0606 on key code read and 0087 on a scanner. Shimmed the stock plug and no issues since. Would happen pulling 40 foot horse trailer merging on to on ramps or going up hill at a slower speed then having to ask for more going up! Til i figured it out if I pulled over and shut truck off and did the key trick to read and reset codes light would stay on but regained power. Light would go away when I unhooked from the trailer and drove a minute. Was really frustrating and annoying
I'm a owner-operator hot shot driver that does his own mechanic work. I brought a 2004 Topkick 5500 I'm looking for a scan tool that will work with the truck. I have tried a few and most of them don't recognize my truck.
This part is impossible to remove. The company that made it was so cheap they couldn't let the threads stick out just a few more mm. I'm considering removing the entire fuel rail just to get to this part.
+Duramaxtuner Got replaced with 1 that is the same as the 1 that yall offer, just drove it and it's doing the same thing, blowing black smoke, no power, going into limp mode and won't do over 2000 rpms, what do I do next....HELP
I got same issue lb7 nothing over 2000 rpm fprv or cp3? I'm getting no code currently had to put new o rings in filter housing due to leak there thought that was the issue but didn't fix the 2k loss of power after 10 minutes of running
rootedflunky1 no that is caused by your fuel filter housing. You just need to rebuild it. It’s like 20 bucks comes with new spring seal and brass fitting.
rootedflunky1 same thing happen to me about 2 months ago. I rebuild the fuel housing out on my drive way and it was missing one of the o-rings in there. Didn't even have to take it completely off my lmm let it hang and put back with new seals and bam! Running like a champ.
I had same problem a couple of years ago, leaking around primer, also wires were broken for the heater on the top of the filter housing. Could not repair wires , ordered a new housing from dealership and problem solved.
I have an LLY with an LBZ Fuel Pressure Regulator. Starting to get a sporadic idle where it usually sits around 4.3k rail pressure and then it drops to 2.5k -3.5k and then shoots up to 5 or 6k then drops down to normal. Is this a relief valve issue or a FPR issue? I have not re-tuned the truck since installing the LBZ Regulator
Used a regular 18mm Craftsman wrench. Used the boxed end on the wrench. Tapped on the open end of the wrench with a brass hammer.
Tap tap tap until it came loose.
Installed plug same way. Tightened by hand as much as I could, then tapped it over a quarter turn with the brass hammer.
Where is the location of it
Put this on my 07.5 LMM holy crap this made a big difference in how my truck ran!!! It even shifter better!!! I did however crack a rib getting it loose so I believe Sasquatch put mine on! 😂 but I’m good now
I just replaced this valve in my '07 LBZ at 114,000 miles and before the codes had a chance to appear - preventative maintenance pays... Thanks!
Good video! I know an even smaller part that can cause grief, the injector check ball! 😄

Please do ASAP, thanks.

Yes it does. It is under the turbo horn on LB7.

Lots of questions about LMLs
I have 2015, same problem, but cant find any videos
It's on the front of rail drivers side
The back port is a sensor, the front is valve
I cant find anything on how to get in there, may have to take EGR off
So is it a prv or just a plug?
Could this make a crank no start on an lb7 it was running great then gave it two sharp rpm revs then it died and won't start
No, but there are a multitude of other fuel starvation points that could. Log rail pressure vs desired rail to determine if it's fuel system related.
Will having the stock plug on have to do with my ac compressor shutting off I have a early 04 lb7 and I realized every time I step on it my compressor shuts off.
2002 lb7, is that the same fuel pressure relief valve? Is it in the same location?
Thank you
Does the LML has it too?
I'd like to know also
Anyone get a answer to the lml
Lb7. Zf 6speed.
Is it a more tense scenario?
Multiple revs up and abruptly down again at full throttle. In rapid succession.
Maybe the sprung version of the plug is more desirable??
We have never had an issue.
Can this cause p1089?..
I had this code return today P0087 w/Low Power Mode. This happened while towing 9,000# 5th wheel.

What about the risk of blowing off the injector tips because now you have no way to vent the pressure which is how the system was designed?
Tony Turner the rail plug they sell still operates as a relief valve. However it is a higher quality and a little stronger
@@andrewfarrell4312 no thats definately a plug.. not a sprring

I have a 2011 duramax 6.6 that is having these issues but looking at the end of my fuel rail on driverside I see a electrical connector. So any advice?
2011 uses an electronic relief valve. It's a pretty robust design unless debris goes through it (in which case you've got bigger problems).
Can I use it on my 2004 lly stock

Does the trans need a relearn after this
This has nothing to do with the transmission.
Does the LML have the same or similar problem?
Actually, the LML has an electronically controlled valve.

Can a bad relief valve cause me to get high fuel pressure?
No, generally that would be a regulator issue.
My 2009 ram 4500 is smoking and throwing p1011 codes and the p000 one .. is this the issue ?
CHRIS ULLOA
I can't go 2000 rpm goes into limp mode no codes and I cant even hear my turbo . No p0087 or p1093 code . What could it be ????
Have you data logged the truck or had a scanner hooked up while the problem was happening?
+Duramaxtuner I have an insight cts2 and nothing just two glowplug codes
Give us a call for more detailed assistance: 815-568-7920.
do you fix it? I'm having same problem in my truck
Try changing your fuel filter!
What about code p0088? Will this fix it?
I have an 06 3500. I get a ticking noise for a couple seconds then truck blows white smoke then it goes away. Could this relief valve cause this to happen if it's bad
There are a few things that can cause those symptoms. A new fuel pressure relief valve is a good idea, for starters. Can you call us so we can help you kick around a few other ideas? 815-568-7920.
Can it be tested at home?
What could cause similar issues to this on a LB7? Got my LB7 tuned and it ran great for 2 weeks, now it keeps throwing a P1093 code and the fuel pressure drops significantly WOT. The second I let off the throttle the fuel pressure jumps up to where it should be. When I give it half throttle it runs as it should
We may be able to offer a few other ideas - why not give us a call - 815-568-7920.
Did you figure out what was going on my lb7 is Doing the same thing
I have a 03 LB7 with a Fass 100 lift pump on a new motor with 1200 miles since dropped in.Motor shuts off no codes.Cranks right back up.Any clue
How about on a 3116 cat engine
Does this not apply to an Lb7?
Correct - it does not apply to LB7.
So would you recommend putting it on a 04 lb7?
Can you use this part on an lb7
Is the relief valve an issue with LML models, I'm getting ready to do a full delete and I don't want to create any issues with the added power. Granted I'm guessing around 200 horse and 400 lbs of torque increase, but like everyone else I'm looking for better economy and reliability as well.
You really need to talk to us before you delete your emissions equipment. Click here and we'll get back to you ASAP: goo.gl/SBPty9
lbz recommended torque specs?
This DOES NOT apply to an LB7. There is no fuel pressure relief valve on an LB7. For the Duramax trucks that have the relief valve, I saw 74 ft. lbs. somewhere for this little guy! Just crank it on there like the good men at Calibrated Performance said to.
74 is correct
@@jx906 He said LBZ, not LB7. But thanks for the torque specs info.
Torque to spec. What is torque?
does this apply to the lb7 eng.?
No.
No lb7???
I my truck is 2014 Dodge Ram 1500 4.7 gas engine ..I don't know where my fuel pressure relief valve is. Can you help ?
I think this is for diesel engines only but I could be wrong
How to replace a fuel pressure regulator on a 2002 freightliner sprinter
Today I got the p0087 while towing and forcing the truck abit uphill and truck went into limp mode, is there any risk on replacing stock valve with this? I drive a 2012 ram 3500 6.7 full stock.
Daniel had the same exact thing with mine. 2011 ram 3500 after I deleted! Had p0606 on key code read and 0087 on a scanner. Shimmed the stock plug and no issues since. Would happen pulling 40 foot horse trailer merging on to on ramps or going up hill at a slower speed then having to ask for more going up! Til i figured it out if I pulled over and shut truck off and did the key trick to read and reset codes light would stay on but regained power. Light would go away when I unhooked from the trailer and drove a minute. Was really frustrating and annoying
Taylor,can you explain the "key trick" please?
"$50 part" meanwhile on a 24 valve it's a $300 part and does the same exact thing...I love my Cummins and all, but sometimes man
I'm a owner-operator hot shot driver that does his own mechanic work. I brought a 2004 Topkick 5500 I'm looking for a scan tool that will work with the truck. I have tried a few and most of them don't recognize my truck.
GM MDI Tech2 would be the most complete but, comes with a price tag. An EFILive AutoCal/SPADE would work for basic scans and data logging.
I have a 2008 Topkick(C4500) with an lmm motor. Is there a scan tool for my truck where I can read and delete codes?
Can we use this on the lml motor
DMAXMB Mb that’s what I’m asking myself 😂 16 lml here
Here people talking it went to limp mode my just stoped an won't start do they do that to
This part is impossible to remove. The company that made it was so cheap they couldn't let the threads stick out just a few more mm. I'm considering removing the entire fuel rail just to get to this part.
Price 540.00 at the dealer
+Jermain Jackson LOL, for a valve with a spring that is going to fail. That is crazy, the race plug we sell is just $50 + shipping.
+Duramaxtuner Got replaced with 1 that is the same as the 1 that yall offer, just drove it and it's doing the same thing, blowing black smoke, no power, going into limp mode and won't do over 2000 rpms, what do I do next....HELP
Sounds like it could be a weak pump. I would start my diagnosis there.
I got same issue lb7 nothing over 2000 rpm fprv or cp3? I'm getting no code currently had to put new o rings in filter housing due to leak there thought that was the issue but didn't fix the 2k loss of power after 10 minutes of running
JR Harlow What ended up being the problem
Is there one for an lb7?
Yes but it is in the function block with the pressure sensor and not in one of the rails
I'm having fuel pressure loss when my lmm sits and I have 2 prime it. Could this valve be the problem? I'm getting no codes
rootedflunky1 no that is caused by your fuel filter housing. You just need to rebuild it. It’s like 20 bucks comes with new spring seal and brass fitting.
rootedflunky1 same thing happen to me about 2 months ago. I rebuild the fuel housing out on my drive way and it was missing one of the o-rings in there. Didn't even have to take it completely off my lmm let it hang and put back with new seals and bam! Running like a champ.
Sergio Flex5 ...... I replaced the water separator sensor and that fixed my problem... Thankfully I didn't have 2 rebuild the housing.
I had same problem a couple of years ago, leaking around primer, also wires were broken for the heater on the top of the filter housing. Could not repair wires , ordered a new housing from dealership and problem solved.

Got a customer that installed that plug on his truck due to the P0087, he cleared the code with his tuner... Light came back on.... P0087. Woohoo!
I have an LLY with an LBZ Fuel Pressure Regulator. Starting to get a sporadic idle where it usually sits around 4.3k rail pressure and then it drops to 2.5k -3.5k and then shoots up to 5 or 6k then drops down to normal. Is this a relief valve issue or a FPR issue? I have not re-tuned the truck since installing the LBZ Regulator
Call you give us a call at 815-568-7920 - we have a few questions to ask.
Rob Galles having the same issue same truck lly. What was the fix? This or fpr? Thx
Thanks for the video Regards
