Fuel pump check

Grant Eldridge · 03-03-2013, 01:57 AM

Lots of good information posted here! I raced a 396 E/SA 325 or 350hp combination. I started with a Holley blue and #8 lines with the Holley regulator, just like the system described . Next I switched to Holley black, better Magnafuel deadhead regulator, #10 line, but the car still seemed not quite right on the top end. Finally, in my third system, I have an A-2000 Aeromotive pump, a return system with Aeromotive regulator and #10 lines both ways, and a #12 section from the regulator to the Q-jet to supply additional volume of fuel to the needle and seat. I know this sounds like overkill, but the Q-jet as explained above needs a lot of volume and not high pressure, or the float cannot overcome the higher pressure and the single needle will fail to seat, you will have flooding. This system will deliver a gallon in less than 15 seconds. If you spend the money once, and do a top notch system, you can then depend on it and concentrate on other things. I tried doing this the cheap way, guaranteed I wasted a lot of time and money re-doing the system several times to do it right. Plus, you can chase tuneup issues such as a slight top end miss or pop endlessly that are actually the result of lack of fuel volume. Just my two cents...

It appears that the Aeromotive "SS" pump has the same specs as the Holley "Black" pump,which is what I am using now,with an Aeromotive reg.
I am thinking of upgrading my pump.It seems to me that the Aeromotive A 2000 would be a good/better choice than a "SS".
Any thoughts?

You are correct. Again, I have yet to see "too much fuel pump". Most people who put a really big fuel pump on see gains in MPH, and improved consistency. We took a BG 250 off and put a MagnaFuel 500 on, the car picked up some MPH, and it is deadly consistent. And that's with a 4150 style 4 barrel.

The small block stick car we had was equipped with an Aeromotive 2000, which fed the Q-Jet easily. Although we never went through the engine, so it was tired and a little slow, it was stone consistent, and never did anything odd at the top of the track. And it still ran a decent MPH despite being dead tired and outdated.

Although the specs are similar for the Holley "Black" and the Aeromotive SS, the Holley is no where near the SS. The SS pumps more fuel, more consistently, with greater longevity than the Blue or Black pumps.

The A2000 is an excellent choice also. This pump easily runs some of the fastest Q-jet Super Stock cars in the country.

What experience or opinions are there on the Holley HP150 pumps? I realize there is a Holley Black pump but I've seen people look at the HP pumps and still refer to it as a black pump. Holley had some issues with this pump and overheating initially but seem to have that corrected for some time now. Yes they too are black but are completely different animals.

I had a Holley Black on mine to begin with, with #8 lines, in a return setup. Its only a little better than a Blue pump. I went to a BG280, and it picked up a little in the back half with the extra vol. Changed it after having trouble 2 time with the 280 and put the Magnafuel, and went to the #10 lines and a Magnafuel reg. Picked up good (.06, in worse air) in back half ! Volume is the key, with a fuel bowl 1/2 size of one Holley bowl. "Stacking" fuel. is a definite requirement with a quad.

What is the correct way to set-up this by pas system?
