Fuel system

Joe DeMarzo · 06-17-2013, 05:14 PM

After changing 2 fuel regualtors I discovered my fuel pump decided to go out of town while I was racing at Lebanon Valley this weekend. I had too much fuel pressure from the pump.

I plan on buying new pump, regulator and what ever is trick. I am looking for insights on what is best system for a Chevy II, 350/200 stock eliminator car.

Open to all suggestion before I make my decsion.

Thanks for the insights.

I don't think you can go wrong with the Aeromotive for both cost and reliability. I bought two so I would have a spare but so far, after fours years I haven't needed it. I have a Magnaflow in the box waiting but see no need to use it at this time. Jim

I also have used the Aeromotive pumps and they worked well.

Installed an A1000 in my EFI Firebird after the pump that was in the car failed up at Lebanon Vally.....It was a similar pump made by Paxton.

Used an A-2000 in my dragster and it worked fine on gas or alcohol

Probably overkill for a Stocker but it never hurts to have a fuel system that is better than you need.

An A-2000 pump uses a return line at the pump back to the cell and pressure can be set at the pump before the regulator. I used 25 lbs at the pump.

I used a MagnaFuel regulator....pressure was rock solid....

pick your posion. Holley, Mallory, Magnafuel, Product Engineering or Aeromotive, they all have a model that will get the job done. Nothing trick needed and I never subscribed to the thinking that you need a pump that can fill a pool and lines as big as fire hoses.

Ran a Mallory Comp 140 pump and dead headed regulator for many years feeding my 700+HP 468 from the stock/unsumped gas tank without issue.

Joe I run Aeromotive......never had a problem...used the same pump when I ran the Qjet but with different regulator and a return line...my old 624 motor ran the best numbers with that setup

Joe,
D/SA 396/350 68 Camaro.
Took off an old Mallory pump, regulator and lines, replaced entire system with Aeromotive.
A-2000 pump, along with their regulator and new lines, picked up a tenth.
Granted the other stuff was old, but still, a TENTH?
Best part was the assistance from Aeromotive when I did have a question. great customer service!
Very easy to work with at the track.
and the best part....... (drum roll please.....)
Their contingency check is usually one of the FIRST to arrive. And in this day and age, that accounts for a lot in itself (IMO)!

Unk

FYI, You could almost run a stock mechanical fuel pump with a Holley and get away with it. Dual inlet, and plenty of bowl volume.
Running a single inlet carb, with very limited bowl volume has unique needs that are different than a Holley.
If you never raced with a Qjet,AVS,THERMO Quad, ect, and or used a Data recorder, or a wide band O2, you may have a hard time believing this. Engine size, HP, car type will dictate what an engine likes. My brother has a 20 year old Comp 140 pump that came out of my car, in his 10.50 bracket car all day long without a problem. I have not experenced the same results.
Race on while we still have classes to race in.

whichever way you go make sure that you do not overfuel the system.......too much fuel can be worse for your engine's performance than being on the "short" side. You'd be very surprised at how little an amount of fuel your engine (in particular) requires to operate at its potential and how many guys are "killing" their system and ultimately performance with too much fuel..............
