So'So your not gettin any fuel out of the return when the truck is turning over?

no sir none at all

Alright soooo it ran when you got it and now it doesn't run. What did you change from then to now? It might be time for a trip to the Cummins shop If your not getting any fuel out of the pump itself.

ok im back to the lift pump being bad i hooked a small electric fuel pump off of my old gas motor and i had fuel to the pump and coming out the return so hopefully on monday i can get a new lift pump and all will be well. would hooking up that electric pump inline with the new mechanical pump be an advantage of any kind just a thought.

the electric pump would need to pump more fuel than the mechanical pump or you will starve the pump and it will go out..... thats what i heard anyway cause i wanted to put a lift pump off a 24v on my truck

I never thought of that, so defitley not adding the elctric pump lol

Or your could get an AirDog and ditch the factory setup all together... Thats what Im gonna do when I get enough coin :pca1:

Yea i would love to but i am spending to much on this all ready. I ended up replacing the lift pump and deleted the fuel heater. I got it to start but it was a short victory it ran like hell for a min and died and wouldn't restart. I pinched the ofv line and it was hittin like it wanted to start bt wouldn't. I think im just going to get a new ofv tomaro and go from there.

What fuel tank and fuel canister/pickup are you using?

its all new stock replacement 78 ford and i have my return line spliced into my fuel filler neck.
