lift pump troubles?

[david1938]

I just returned from a trip of 2000 miles, most things are ok. But I am driving a 04 dodge 1 ton with duel wheels and I am getting lower mpg than I did with my older dodge (1998) I used to get 14. 5 fuel now I get 10. 3

with the new fuel pulling the same load, a 11000 lb 5th wheel.

when I am pulling up a steep hill and have to shift to 2nd I try to keep the

rpm below 3000 rpm and prefer about 2500 rpm. after a bit of running at 3000

rpm the engine would start to cut out like it was running out of fuel

that is why I cut back on the rpm. this happened ever time. Do you think it's the life pump? or some thing else.

2004 1 ton duelwheels

4 door long box lava red but all stock except for the trim chome.

Dodge is a great truck with the cumming engine.

tell us what is on the truck (any mods) and is there a check engine light, if so what are the codes.

The truck is stock, only because I am chicken. Tha check light did not come

on. however I would like all the 700 hp that you have.

Could be the lift pump. Best thing to do would be to put a fuel pressure gauge on it and see what's going on.
