  1. 04.5-05 LLY Duramax Powertrain
    Hi all, I’ve got an 05 that limps. When I bought the thing in December it limped, and its got a new set of injectors and a new cp3 (under my ownership). My questioning is of the lift pump. The truck works mostly fine around town, I can’t do more than 75 without sending it into limp mode because...
  2. 06-07 LBZ & LLY Duramax Powertrain
    I just fully deleted and tuned my lbz duramax will the HSP high flow bundle kit, and for some reason the truck now gives a check engine light (P0087) after 3,000 rpms. And I cannot figure out the problem. I just brought the truck in august with 275,000 miles on it. And it does have a airdog...

    Man I am honestly impressed. Went to change the screen for my inlet valve on the CP4 Today and after 170k miles this is what it looks like with a lift pump on the truck from the beginning. Not gonna say a lift pump saves your fuel pump but I will agree it helps it a ton along with good fuel and...
  4. 11-16 LML Duramax Powertrain
    Hey guys- Question for the masses. I have a 2011 Silverado 2500. It is pretty much bone stock with about 92k. I recently installed an Air Dog 100 (bone stock and not overworking the truck, saw no need for a larger lift pump), and a few days after the pump was installed the truck would not...
  5. 11-16 LML Duramax Powertrain
    Hey guys, long time lurker, but finally created an account due to an issue I'm having that I can't seem to find a solution to (I did search first!!). So, I have a 2015 3500 LML with 285K miles on it. It lived its first life as a race horse puller in the Midewest before I bought it. The truck...
  6. 06-07 LBZ & LLY Performance Parts Discussion
    I am new to the forum and have looked into lift pumps. I was wondering if anyone had any input on the caterpillar fuel filter housing/lift pump unit. Is it any better or worse than getting an air dog or fass pump?
  7. General Discussion
    I'm installing a Fass Lift Pump on my LB7 and I want to combine it with the Beans Sump. I couldn't find any info on what's inside the fuel tank, like slosh chambers or any kind of reinforcement. I would hate to drill the sump hole in the wrong place! For those of you that have done the sump...
  8. 04.5-05 LLY Duramax Powertrain
    I have a 2005 Kodiak C5500 with a Duramax (LLY). Drove it about 200 yards and it died. I could get it to restart if I continuously pumped the primer on top of the stock fuel filter. Got it home and made the following "fixes". New Fuel Filter. I have two DuraMax trucks so I have a lot of...

    My airdog 1 150 went out a couple of months ago, wondering if it is bad on the cp3 to be run without lift? dont want to drain the rail and wear the pump or anything. run stock program dont have a tune
  10. 04.5-05 LLY Duramax Powertrain
    I've been losing prime below a quarter of a tank. So I rebuilt the filter head and it was all fine. I also installed a lift pump and put in a new fuel filter. The problem continues to happen, but only below a quarter of a tank. I can get it to run if i reprime the system and the low fuel light...
