Failing Fuel Pumps

[SSDiv6]

Tom,

You have more than sufficient line size for your application. Also, which regulator are you using?

There have been issues with the Aeromotive A2000 fuel pump rotors wearing out and breaking too. Aeromotive also releases a new pump model, A300 as a substitute to the A2000.
Also, a friend of mine was told by an Aeromotive tech to not run the pump for a long time either.

My preference for pump has always been the Product Engineering or Magnafuel pumps. I believe Magnafuel is the same pump as the Product Engineering. They are robust and the customer support is great. If you run either pump, use their recommended regulator too.

This is the Fairlane fuel system.......the fuel pump has been lowered since this photo and after the first pump failure. I have Aeromotive 4 port Pro-Stock regulator, dual 4 barrels with side hung bowls, 6.5psi. My major concern is I built my hemi car fuel system the same.....using the same pump.

Tom,

That's a very nice neat installation. I am envious. The only issue I can see is the loop in the vent line. I would get rid of the loop. If you get any liquid in that loop it will act as a trap and wont let the system vent. Looks lie the vent in the hemi car is straight.

Ok thanks, good advise, I raised the filter as high as I can and took out loop on the hemi car and will do the same with the Tbolt.

On my car I ran the vent down through the trunk floor using a bulkhead type fitting. The filter might also be slowing the vent process especially if the filter media gets wet from fuel. You might thing about ditching the filter as well. I think by the rule the vent is supposed to be plumbed to the exterior of the vehicle. I would check the rulebook on that too. Hope it helps to fix your problem.

One thing I was told is to put pump behind outlet so G force pushes fuel in pump,not sure how much difference it would make,but I know pumps don't pull fuel well they are made to push it.

BTW if anyone needs parts for BG 400 had a friend got some parts I believe was www.carbs.com,the piece that the vanes rub was ate up they had replacement in steel? had upgraded parts anyway.
Can't remember Product engineering's owners name off top of my head,but he designed BG 400,Grant patented it on him,then designed the Magnafuel style with filter built in.

Tom,
I have seen your car run and I know you do not have a fuel delivery problem.
If you fuel cell was not venting and the fuel filter causing an issue, you would have seen it affect the performance of the car, especially on a high horsepower car like yours.
Your fuel pump is installed like many other racing pumps.

Is that a regulator with return before the pump on the suction side?
