I used a Carter P90091 fuel pump on my Duster and mounted it right above the tank sending unit and routed the fuel hose kind of looped around to hook to the factory hard line. It works fine with no regulator. It's made for use with a carburetor and its quiet or at least I can't hear it with my bad ears.
That’s a great pump. I have used Carter electric pumps for years and that 90091 I have in my 39 ford with a early Vette 283, I have almost 45,000 miles on it and it’s been on there almost 6 years, no issues, and yeah it’s whisper quiet.
If you’re gonna use an electric pumps, wire in a switch that you hide somewhere that switches the ground for the fuel pump relay. That way if you are gonna work on it and need to turn the key on, you can switch the pump off. Plus it’s a little extra security. If someone tries to steal it, they are only getting as far as what fuel is in the carb.
