was the lift pump moved to the tank by previous owner, under warranty etc? (2001 did not have intank pump initially, it was an "upgrade" to repeated failures of the engine mounted lift pump. Many are not satisfied when the pump is moved to the tank). If it is in the tank you can by pass it with a new fuel draw tube to the new lift pump, but I dont think that you can actually draw fuel through the in tank pump.



Others will beable to give more info on the intank pump. I never had mine replaced with the intank, had 4 of the stock ones go out though, which took out my injection pump. I went to a FASS 2 years and 30k miles ago and have not had any problems.



Was the Drag comp a new addition to this truck? Sometimes boxes that tap the pump wire can fry the pump in short order if it is on the weak side to begin with.



Do you know what your fuel pressure is currently and prior to getting the injection pump crapping out?



Is this the truck in your signature line? If so looks to be hopped up pretty good, may just be the nature of the beast when u are sled pullin'



You should beable to find enough reading here on fuel systems/upgrades to let you read straight through 2008!



Hope this helps,
