Lift pump suggestions???
Ive got a 99 24v with a few goodies. (banks high ram, banks exhaust, hx35/40, Edge Juice w/attitude) The truck has 260k on it. From what I can tell after cleaning of some mud is the lift pump on it says FASS HPFP. The problem is at about 1/2-3/4 throttle fuel pressure drops below 10, 8, as low as 5. Im not sure what injectors are in the truck either. (only had the truck for 3 weeks) I really don't want to buy a new VP44 anytime soon so any and all suggestions would be greatly appreciated. I was looking at the Raptor 150... is that gonna be sufficient?

Raptor 150 will work great.

Will I need to drop the tank? Or will the Raptor go directly in place of the FASS? Thanks

Re: Lift pump suggestions???
The raptor will mount on the frame rail.

Ok perfect, so the "draw straw" should already be in the tank from the current pump? Thanks for your help Luke

I would suggest replacing your stock draw tube.

The thought running through my head is why isn't the FASS doing its job? Has the fuel filter been changed? You could contact FASS and see if they could replace/repair your current pump.

your could have a weak spring in the pump, as mentioned above a dirty fuel filter, or other issue. Check the simple problems before you spend money that may not be needed

Sorry I read the original post wrong. I was thinking about the DDRP not the HPFP.
Sounds like a bad spring or a weak pump |
That pump has a I think
That pump has a fine screen filter in the inlet banjo bolt mine did the same thing,had blackbuild up restrickting fuel flow.I agree that checking the entire fuel system on any older truck bigger pick up tube etc. is very good.I also drilled out the holes in the bolt for the heck of it.My fass ddrp stays just above 11psi. 3/4 throttle on stock motor. |
