Holly black fuel pump
I bought a holley black fuel pump and its rated for 140gph and 14psi. Do i need to ruun a reulator? because my buddy told me i needed to have one or run it through the stock lift pump. Why would i have to do that? Thanks.

No, you don't need a regulator and I would definitely NOT run it through a stock LP. That's a good way to fill your crankcase with fuel if the stock LP diaphragm fails.

Yep. 14 psi wont hurt your pump at all, they can take up to 18psi without issue and as NadirPoint said is your diaphragm fails you will fill your crank case and destroy your engine if you don't catch it right away.

I've had a Procomp black (Holley knockoff) on my aux tank for three years, no issues yet. The only thing I don't like about those pumps is they are loud. That pump gets used to transfer the last few gallons to the stock tank after the aux tank runs low and to transfer kerosene a couple times each winter.

Thanks guys!
I called summit racing before i bought it and they said its good as long as i dont run biodiesel in it. Another question. I put my 3200 gov spring in my truck. it runs 10 times better, buy my top speed is only 90mph. with the stock spring it was 85mph. Do i need more fuel? I only have it turned up about 1.5 turns. |
Probably needs more throttle travel to get full fuel.

i took the full throttle screw out
|
Just because the screw's not there doesn't mean the throttle is getting full travel. Have you had somebody sit in the driver seat and floor the go pedal while you watch it? What about moving the cable up to the middle hole on the throttle lever? They are also known to bottom the lever out on the fuel inlet before full travel.

i havent tried that. I'll get back with ya when i do.
