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

We just went to a whole Aeromotive A-1000 system (regulator, filter, etc) with return line. We deadheaded our old system and it seems the fuel pressure is more stable with the return line system. Everything seems OK so far.

Aeromotive owners are racers and stand by their products. Plus made in Kansas City, no foreign junk.

One big issue I had with the Aeromotive A-2000.....and I am sure it would apply to any other real high volumn pump....

Don't use a filter on the inlet side with a smaller than 100 micron rating....or do as I did and use no filter at all......

My pump would cavitate after 10-20 seconds with an Earl's screw together cannister filter on the inlet side.......and the pump was about 1 foot from the fuel cell......with a -10 line and one 90 degree turn into the pump.

Vibrated bad and pressure was totally unstable......
Not enough fuel getting into the pump......

X3 on the A2000 pump. Never had one problem with any of their products.
