CARB Fuel Pump

I had a 383 TPI that went bad and I blew a piston and after fixing it I decided to go CARB. Now my problem is this I have a Walbro 255 Fuel pump from Racetronix that I paid a pretty penny for. I want to know if that pump will work or if I actually have to buy a CARB pump. I already switched the APFR from a Wilban to a CARB one. Is that enough of would I need to buy a new fuel pump. Thanks

You don't need a different fuel pump. You do need a regulator that controls output pressure by returning excess volume back to the tank. Often referred to as a "return style" regulator. Mallory 4309 is one example.

Re: CARB Fuel Pump

Awesome Thanks. Thats the one I ordered to replace my Winbar AFPR. But I just wanted to know that my Fuel Pump just didnt need to be changed to a carb pump.
