HPFP about to sh*t the bed?

[Beans71086]

So I've had been noticing on wot runs that my rail pressure was dropping to about 22500. Changed the filters and it now peaks at 24000 and drops into the mid to high 23s. I'm running the newest spartan 310 and was wondering what rail pressures you guys were seeing. Maybe I'm just paranoid that at 42,000 miles I'll have to replace my hpfp. :shrug:

should beholding around 24.5k. still under warranty right? i bet its getting weak.

 

[Marty]

Not under warranty. Bought in 2007.

Not the opinion I wanted. LOL Any other thoughts?

 

[pog]

is there any difference between frp at wot when the tc unlocked and locked?

 

[Beans71086]

Negative, not that I noticed anyway.

i would bet that your delivery pump is a tad on the weak side.

rail is going to 24k,then bleeds back. weak hpfp isnt going to make it to max rail in the first place.

you need to do a airdog,or something that moves a bit more fuel. your hpfp is over drawing the delivery side.

Hmmm this does make sense.... Maybe is time for Marty to do work on his 6.4 fuel system! oke:

Good luck with that. He's too obsessed with those dinosaurs he runs.

for a 6.4 thats not really ever going further power wise? just do a ad2. keep it simple.

I'd say I'll prolly go with an a1000 setup if it comes down to it.

We're always looking to go for mo powa!

i would do a a1000 or fuel lab if it were me. most people would because of cost.

especially if a ad2 will do what they want/need

The AD2 is fine and all but to set one up properly you'd still have to delete the fuel bowl so that brings the cost up to around 1200ish. I prefer the A-1000 setup that Marty is working on also. I think the Aeromotive pump is better than the AirDog stuff and for the extra money will be worth it in the end.

i agree but most peoples wallet thinks for them...

No doubt, personally if I couldn't afford it I would wait until I could and then opt for the better setup.

 

[Beans71086]

So we have one vote hpfp and one vote lpfp. Anyone else?

 

[Dieselcraft]

Check your base fuel psi. Forced up grade time

 

[Beans71086]

Ten four, do you know if there's a parameter in the dasdaq for that? If I remember right your a ford tech, what pressure should I be seeing on the low side?

 

[Jeff@Spartan]

The DashDAQ won't read fuel pressure. Only fuel rail pressure.
