Aeromotive 1000 EFI fuel pump

[DLinson]

I purchased a new Aeromotive 1000 fuel pump and it is on its way. It says in the instructions online that it needs a 10 AN feed line from the tank to the inlet of the pump. Right now I have an 8 AN feed line since the old pump only had a 1/2" male barb inlet. I'm running 520 HP at the crank. I definitely won't be over taxing the pump. I also purchased the Aeromotive pump controler to pulse the pump at low RPM's.

Do I need to change that line to a 10 AN line? The fuel filter has 3/8 NPT inlet and outlets so I'd have to replace that as well as the fittings from the tank to the pump.

Thanks,
Dennis

I used a 10 from the tank to the pump, and then downsized at the filter from 10 to 8, and ran 8AN to the engine.

8AN should be plenty for 520hp.

I run -8 without issues. If your using the pump to higher capacity, I'd up the inlet to the recommended size.
