Gonna ask a question that I know is not new but here goes. My Street Rod is powered by a 454 bb Chevy. The carb is by Edelbrock model 1404 [new] the fuel pump is also Edelbrock model 1721 also new. The problem is after setting for two days its a crank-crank situation to get the engine to light off. After first crank up it's fine for a day or maybe two. I've talked to Edelbrock Tech and they blame it all on gasoline evaporation. Adding a low psi electric fuel pump between tank and manual pump, to fill the carb, will not work since manual pump is diaphragm operated and not able to push fuel through it. What is my best solution economically and safely short of trashing the entire carb setup and going all EFI. Fuel tank is in the very rear of bed approx 11 feet from manual fuel pump.
