Hi guys anybody out there know the differences between a Holley blue fuel pump and the black? Basically my old Holley blue will no longer keep up with my fuel requirements at WOT so I was wondering if I could modify it like the "black" first or if I just need to look into a bigger fuel pump. From the pictures the two pumps look the same externally but I have never seen the inside of the "black".

Thanks,
Loren

The Black is a 145gpm. I got your PM.
Thanks and I replied back. :)hand

After brain storming with another racer here at work I'm wondering if my electric motor is worn out. The pump is old and has been used double duty skiing, tubing, crusing and racing for more years than I want to admit publicly. :)sphss

my uncle has a slightly used mechanical 170gph holley pump that kept up with his blown 540 , twin dominators he's selling;), no regulator needed. it flows great, no wires:D it has less than 3hrs on it, we've gotta run a belt driven deal on the new set-up to keep up with fuel demand.

Thanks but I do like the electric after running it for so long.

yeah, i remember thinking that myself till i saw the flow map on a holley black electric pump:D at wot, the mechanical 170gph holley doubles the flow to the carb/s compared to the holley black;) don't believe advertising, it'll cost ya a piston:)st

This is just a NA tunnel rammed 467 that runs double duty. No nitrous so I think it will be fine. :)

This Holley Black flows 120 gph at 9 psi. 120 gal x 6 lbs per gal = 730 lbs
730 lbs @ .5 lbs fuel per hr per hp would feed 1,400hp. I wouldn't try it but that's the math. This pump has 3/8" connections it should be able to feed 700 hp with out much of a problem but it depends on the fuel lines, fuel filter and regulator and pick-up tube.



This Holley HP -150 flows 140 gph at 16 psi. That's enough fuel to feed 1,680 hp. Once again, I wouldn't try it but that's the math at .5 lbs fuel per hr per hp. This pump has 1/2" connections. It shouldn't have much of a problem feeding nearly 1,000 hp depending on fuel lines, filter, fuel pick-up tube and regulator


The HP-150 feeds the 565 no problem (935 hp) with -8 lines from the tank to the regulator.

I think the HP-150 cost's about $ 55.00 more.

I ran the black pump on my 467 with no issues whatsoever. Yes, a fuel pump can wear out...I just replaced one for that very problem. It may not "sound" like it's worn out, but put it on a scope and see what the waves look like. It's easy enough to replace the blue with the black...same for same, no hassles, and plenty of pump.

I find that hard to believe if you run them, even the ones in factory cars go out after so long. :p:)hand
:)sphssare you comparing an oem mech with a claly smith, edelbrock, or holley six valve pump? I didn't compare the black Holley to the POS O.E.M. pump that took a shit on my EFI Mustang. They all take a shit eventually, other wise there would be no reason for parts houses, and we would all just go to salage yards for the unbreakable OEM crap(oh shit, I just admitted I drive a Ford in front of Steel, AGAIN)

Nothin wrong with a Ford, someone has to come in second or it isnt a race.:D

If you have one of the old holley blue pumps they are far better than the new ones. I have used one of the black ones and it was a much nicer pump than the blue.
Mines 14 years old so it's been a good one but I think the motors going away. Too many years as a ski boat doubling as an occasional race boat I guess.

There seems to be a problem with some of the new ones.....outer case of the motor comming unglued causing the motor to pile up.
