My fuel pump I have an Aeromotive pump # 11203. and regulator # 13301
I changed from a -6 feed line to a -10feed line with a -8 pressure line up to an aeromotive return style regulator with a -10 return line to the tank.
My new 540 Cubic inch big Block should be in the area of 700HP. The -6 line wasn't enough for the new motor the pressure would drop when the tires hook up. Works great. Spend the money the first time.

I had dual walbro, -8 feed line, stock feed became the new return, 60lb inj, Speed Inc rails, FPR by the rails, and and a rewire kit from Speed Inc. On stock motor, 10psi car made 530+rwhp 595rwtq. There was alot more left in the fuel system but I didn't want to push it to much.
