I have always found it to be much easier and faster to unbolt the bed and lift that off with the hoist. You don’t have to manhandle the tank or disturb everything around the tank including fuel lines. Injector return rates aren’t fun to test on these trucks but this truck would be a good candidate to test them on given the issues you have had and the miles on the truck. I would personally test that before throwing a new CP3 at it.

I think you're gonna need injectors my friend. Ive been fighting the same exact thing with my LMM. The injector return rates were fine until I towed heavy in the summer heat. The fuel gets hot, the return rates spike and bam. P0087 reduced engine power. I installed new injectors and an AirDog 165 5g ( bought it off your website btw) and we are good to go. I also fired the parts cannon at it to no avail. I wish i wouldve just replaced the injectors right away.

My LML Duramax did this to me twice. After the 2nd manual regen at the dealer, I had the DPF removed and had it tuned so the electronics wouldn't complain. A couple of months later, I had all of the rest of the emissions taken off and it is never been better. It came with the CP4 fuel pump, so I converted to the CP 3 while I was at it. Fortunately, I live in Texas where they only do safety checks on diesels, not emissions.

I got an 08 GMC Duramax. Bought it slightly used in 09 started working the known issues to make the truck completely reliable. I deleted the DPF and EGR functions, did a reroute of the PCV and added a FASS lift pump and fuel filter delete up front. Then replaced all fluids with synthetic. A few years ago I got very tired of the stock 26 gallon tank and did an S&B 62 gallon tank. The truck has over 200k on it and I would not think of getting rid of it. Runs perfect and pulls everything I got without knowing it is back there.

Did you ever solve your issue? I have a 2007 GMC 2500HD Duramax, currently with 213,000 miles & it’s been doing this for past couple years. I put in a fass fuel pump system a year or so back in hopes to solve the issue, it seemed like it helped for a while, But then it started again. If I pull a horse trailer loaded, locally within an hour or so, it’s fine. But when I travel & I’m moving along pretty good cruising at 75Mph, As I start to head up a small incline… putting a. Bit more strain on the motor, I can feel it go into limp mode. If I baby it I can continue down the road at 60-65mph until I get to next exit, But it won’t go past 2000 rpm. The first few times it did this 2+ years back, I just thought it was bad fuel or a faulty fuel filter, so I replaced a few of them unnecessary. Then I figured as you mentioned, if I pull over, shut the engine off for about 3-5 mins, Then it’s good to go for another 150-175 miles. I don’t know if it would go into limp mode without a trailer because I don’t drive it much during the week & it’s all just local driving. Mine is all factory, except for the Fass lift pump & filter system, So I would assume it may need injectors? But even with well over 200k miles this is engine is very strong, So no sign of any struggling or loss of power under normal driving conditions, Other thing I’m considering is the CP3 pump, Just don’t want to replace parts unnecessary.

I few Months Ago I had the same issue on my Truck. So after watching so many Vedeos on KZitem I found one vedeo that I had watched about the Ignition Switch Solenoid ... I took it apart and cleaned it out. I found out that the "Resistance" on the Switch Solenoid goes out after it heats up. So I went to O'Reilly's Auto store and bout a new Switch Solenoid, after installing it, Limp Mode went away, no more transmission Problems, like "Shift Inhibited" that went away, check Engine light went off. So After I also changed my transmission fluid out, both Filter' from my Allison Transmission, and now my transmission shifts so Smooth. I was going of from the process of Elimination, where I started with a few electrical Diagnostics and Finally I tried the Switch Solenoid..... it's an option ! If someone is have those issues, it Drove me Crazy and I felt so Frustrated where I actually thought it was my Allison Transmission....I began to panic because I didn't have Thousands of dollars for a new Transmission...where in fact it was a part which cost me less than $ 50.. Dollars....my mind feels so relieved now, that I figured out what the Source was through Simple Electrical Process of Elimination....

I just got mine back after having very similar issues but only when outside temps where high (above 85 F) and while towing.

The best way to tell if your injectors are returning to much fuel without doing the time consuming bottle test is your will always have very high fuel temps . Way above normal .

Hey truck master, you are missing a important key element when repairing. The owner hauls a trailer. While testing a truck that hauls a trailer, you also need to perform test with a trailer that is empty and loaded. I'm talking from over 15 years of experience on working on trucks and including big rigs. I'm not bashing you or anything like that. You are doing a good job repairing vehicles but gotta pay attention to customer details. For example how they drive, what the vehicle is being used for, etc. I want to see you excel at what you do. Keep up the good work.

I had the exact problem with a 95 f150 6 banger(gas). I changed fuel filters multiple times on my back the road. Filter wasn’t dirty after the first change but thought maybe it’s a dirty tank so I even blew air back into the supply towards the tank thinking it’s a tank sock dirty. All didn’t help! I traced every inch of the fuel line and found something I had never seen before up by the firewall next to distributor. Too tight to get to it on the road so I banged it with wrench. That fixed it! Had double power from there on out too. I believe it was because I used fuel injector cleaner and it locked something up inside that little regulator? I think I heard you say something about a regulator (I know that it’s nowhere near the same type system but if there’s a regulator and he added injector cleaner. Maybe! Idk but worth a try.

Not to bad mouth a product , but I just purchased a completely new Fuel filter housing & filter assembly for my LB-7 & saw Nothing but bad Reviews on those Henkyo filter set ups !!! Just my 2 cents here . I paid the extra cash & bought a new Racor / Parfit OEM setup for mine as it’s been on truck now over 20 years & I rebuilt the Pump head once about 5-7 years ago. My truck only has an issue when shut down after a long run in hot weather. Sometimes it just dies after re-starting after about a 10-15 minute period & I have to pop hood & re-prime it & other times it has No Issues. The new filter head assembly with new filters for Airdog lift pump are all going on hopefully this weekend and I’m crossing my fingers this will solve my issues . The Edge CTS-3 has shown NO rail pressure issues running under any loaded conditions & Actual pressure is very consistent with required rail pressure at any given load & speed . Only acts like it has a vapor lock or restriction after hot & sitting a few minutes. Give it a 1/2 hour cool down & the damn thing starts & runs fine every time 😐. C-ya on down the road … 🤞

Been through this ended up replacing all fuel lines adding a 165 air dog lift pump deleted the fuel lines on the engine and deleted the fuel test port and added a cp3 hi flow kit with a ported fitting and a new fuel filter head assembly since after rebuilding the stock one I still wasn’t happy. And yet was still getting p0087. Come to find out one of the first things I ever did the Ppe fuel race plug wasn’t seated in 100% and letting diesel into the return lines anything past 20k psi there for throwing it into low fuel pressure and I tested this by disconnecting the return line off the plug and ran my own 3/8 line down to a clear water bottle took it for a drive got it into limp and saw the bottle was over flowing full so diesel was getting past the plug. Fixed the plug and haven’t had a problem since. But I also replaced the whole fuel system except for a new cp3 but did a ported fitting and new fuel pressure regulator on the cp3.

Deleting your trucks when you are a shop owner would probably put a target on your back with the EPA. Their fines kill diesel shops.

Is the L5P known for the same issues? I have a 17 Dinali 6.6 L5P Dura max in low power mode right now

I have a 2009, too, with 225k miles, and I am contemplating on doing a full delete also. I've had the cab off since June fixing all the leaks from the egr cooler. Please help me to know what year of coldside down pipe I will need. I would like to buy WC Fab bundle 1. Thanks P.S. I have already purchased the LB7 uppipe from PPE.

@@TruckMaster had a work truck 07 LBZ have similar issue and so much money thrown at it, come to find out we had a common denominator of being everytime Indian reservation diesel was used. Drained the tank Went back to our sonoco station and never had an issue again. It was all to save .31 cents a gallon which for the headache wasn’t even worth it and therefore never get gas or diesel at one ever again

100% delete it. The emissions restrictions on any vehicle is a joke. It does not protect anyone except those who have a vested interest in profiting from the regulation.

Emission system is not giving him any trouble. Leave it alone he needs all the money he has to fix the fuel problems. Nothing that’s wrong with this truck has anything to do with the emission system. I will get rid of this truck. It’s time to go. It’s just a money pit and it’s not reliable and you don’t trust it when she don’t trust the truck it’s got to go.

@TruckMaster yessir I did. The fuel line that you essentially replace is just a solid fuel line that goes from the tank to the motor. There's no connection behind the fuel cooler
