Tim,
I had a 250 engine in my 1963 C10. Factory tank too. For some reason the carb would be starved for fuel at highway speeds after 10 minutes of driving. A new electric fuel pump from eBay cured the problem.
You want a simple electric pump that delivers 4-6 psi. No return line is required. If the carb float is set properly and working then the pump will not flood the carb or intake with fuel.
I hooked mine up so it bypasses the mechanical pump.
If you turn the pump on manually then make sure it doesn’t stay running when the engine is off. It’s possible to flood the crankcase with fuel if the carb float isn’t working properly and THAT’S DANGEROUS. The same risk can occur if the pump turns on via the ignition switch. If the engine stalls, the fuel pump could continue pumping fuel past a faulty float valve and flood the crankcase with fuel.
I hooked mine up to a separate switch on the dash. Worked fine. Cheap pumps are noisy. Spend your money wisely.
