Carb Fuel
does my car need a fuel pressure regulator if it has the original carb but an aftermarket electric fuel pump?
i have a 1987 jeep wrangler that runs rich and a bit rough. the guy i bought it from left the original carb on there (it has a straight six engine) and put in an electric fuel pump. It came with a manual one. now it runs really rich, and he said it needs a fuel pressure regulator, which the jeep did not come with. is he right?
Yes you'll definitely need a fuel pressure regulator to regulate the fuel going to the carb. Also be sure that the electric fuel pump is mounted in the rear by the tank. Unlike mechanical fuel pumps which pull or suck fuel, electric ones push fuel and if it's not mounted as close to the tank as possible, that too can present problems. Good luck and hope this helps.
