Lift Pump Location

is it in the tank ?

 

What year? And is it OE or 03-04 upgraded?

 

Depends if it was upgraded within the last 18 years. Not many truck out there that have it on the canister anymore.

 

This is a 2004.5 [because it has a DPF can in the exhaust pipe] and is completely stock. My 2004 has a small lift pump attached to the fuel filter assembly. The 04.5 just has a banjo fitting attached to the fuel filter assembly.

I just read my first post --- and I forgot to tell you what truck I was working with.

 

Sounds like you have the in-tank lift pump then, which is good as they have proven reliable.

It's a catalytic converter. No DPF on any 5.9L truck. The DPF started with the 6.7 in 2007.5.

 

OK This truck runs out of power real bad when put under a load like 30 mph pulling a travel trailer up a hill. Somebody said -- Start by replacing the lift pump in case it is running short on fuel. i might just do it. The truck has 266 k on it and I have no history at all

 

Check your boost.
Forget the lift pump.

I'd almost bet you see only 15psi under load.

 

As Ozy said. Changed your fuel filter lately ?
