    I'm putting a carburated 350 engine in an S10 that had a 4.3 tbi engine. My questions is should I use the intank fuel pump and put a pressure regulator inline before the carb or change the piping and use the fuel pump on the engine. I'm also not sure all this will tie in with the rreturn line of if I'll even need it. I've also found information telling what size resistor I can put in the 12v line to the pump to lessen the voltage to drop the pressure although this sounds kinda out there. Give me some help guys.

    TBI pumps are low enough pressure that you should be able to use a regulator to reduce fuel pressure and direct excess back to the tank via a return line. If you reduce voltage to the fuel pump you're only asking for an early grave for the pump.

    OK, do I need a regulator with a bypass line or no bypass?
