Is it better to have a independent fuel system or y off one big pump in the back of the car. Reason being is that i have a 1 gallon right now for the fogger and i am adding a plate. I have a holley blue right now and wanted to know if i should sell all that and just buy a big pump for the back. If so what pump should I get?

For me something about a fuel cell in front of the car turns me off. I have used one big pump in the back of the car with fuel cell with no problems.

I am doing the rear fuel cell, with one big pump to support both nitrous and motor.

but then again I am building what we think is a "true" nostalgia prostreet car. so we feel the rear pump/cell was the way to do it in 1990 pro street so thats what were doing.

I've been using a single pump in the rear this year due to Monty's suggestions last year. I found out for sure you want at least 32 psi at the rear pump, or the G forces will tend to drop the pressure down more than you want at the nitrous regulator, especially on 10psi + solenoid pressure tune ups.

I'm currently using a Aeromotive A2000 dead headed but am getting ready to see what effect a full return style will have. Pressure is now rock steady at the fuel solenoid but I can definitely see the effects of the G forces on the pump pressure. Other cars around here are using the A2000 rear pump dead head setup spraying 500+ going around 8.10's and seem to be working ok for them. But I have no idea what their pressures are doing down track.
