have 91 rs camero with v6 putting in a zz4 with a hot camshaft want to know if the electric fuel pump will still work without the computer to supply feul for the carburator?

youll probly want to wire a switch to supply the power to the fuel pump. The fuel pump is just an electronic motor, so if you run power and ground to it, it will run, you just need to figure out how to turn it on and off. dash mounted switch probly is just as good as any other idea.

If your running a carb on your ZZ4 you will need a fuel pressure regulator cause your electric pump puts out way too much pressure for a carb. I have seen them in Summit for around $100. I'm not sure on the exact pressure but its probably over 30psi. A carb needs around 5psi.

i just found the power to the fuel pump, disconnected the relay and ran an in-cabin switch. that worked well.. also about the fuel pressure go to summit grab a holley one for 26$ itll work perfect, idk where the 100$ comes in thats probly for the pro ones, also ur need to regulate 5-7 psi from the 32-36psi coming from ur electric pump.
