How to Install an Electric Fuel Pump in Your Classic ChevyIf you look at an older car with a carbureted engine, you’d most likely find a mechanical fuel pump. Controlled and operated by manual means, mechanical fuel pumps were phased out in favor of electric fuel pumps. This is because electric fuel pumps do a better job delivering precise, high-pressure flow rates that offer max horsepower to the engine and meet the stricter emission requirements.Not only that but electric fuel pumps are smaller (which means less engine bay clutter) and easier to work on.If the mechanical fuel pump in your classic Chevy is either about to give out or not giving enough power to the engine, upgrading to an electric fuel pump is the way to go.Photo credit: Bull-Doser Upgrade OptionsThe first step is deciding what you want to do with the mechanical pump.

This is arguably unnecessary because electric fuel pumps are designed to last a long time.2. Remove the mechanical pump and replace it with an electric pump: If you’re looking for a simpler solution, this is it.
