I've had good luck with the Carter electric pumps. Here is my go to;
carterengineered.com
Always had good luck with these. Same design for over almost 40 years. Had one on my 57' Chevy back in the mid 80's. Now have one on my '76 K20.
I do have a fuel pressure regulator that has a return on it, so any overflow returns, just as the original mechanical pump did. This ensures I have both fuel recirculation to help keep it cool and consistent fuel delivery at the carb.
Here is the fuel system set up from the tank to the carb on the '76.:
Tank (Stock) - 100um filter(Wix) - Selector Valve (Stock) - Electric Pump (Carter) - 10um filter (Wix) - Regulator (Holley) - Carb (Stock Qjet)
I mounted the electric pump near the selector valve so it is lowest in the system and primes easily.
Everyone has their own experiences/preferences, but I haven't run a mechanical pump in 40yrs. I run this Carter for any carbureted vehicles. Oh, and for fuel injection, I'm just fine with the inline pumps. I ran an inline pump on one of my Holley fuel injected cars for 20 years without a single failure. Yes, the factory cars do run them in the tank, but that doesn't mean you can't run them inline.
