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.
