Fuel Pump Configuration

[bigjack]

I'd like an arrangement that would provide for direct port NO2. What effect would an after-mkt.,additional(to stock, in-tank) pump placed IN LINE with the stock pump have? If not sufficient/recommended, how can the out-of-tank pump be connected to the tank? Thanks, Jack

I use the Barry Grant EFI pump external,that puts out 125 psi ,that is not necessary then you have to get an Aeromotive regulator that reduces the 125 psi to 4 to 7 lbs.You will have to remove the in tank pump and cut a hole on the other side of the return line and run another line and braze in the line to do it right.
You can't run an external pump in line with the in tank pump been their done that.Be careful when brazing you could burn your wire for the gas gauge sending unit.
