Electric Fuel Pump Advice

I need someone to give me the lowdown on using an electric fuel pump vs an OEM mechanical type. I am running a 350 with Edelbrock crossram and 2 Holley 450's. No racing, just cruising the street on weekends.

Re: Electric Fuel Pump Advice

You just need a way to feed the pump(sump or pick-up tube/hose). I've heard of people using the stock fuel lines going up to the front, but you could always just buy some 3/8[or bigger] fuel line and route it to the front how you want it. You'll probably want to run a regulator at the front near the carb depending on what pump you use. Some pumps put out enough pressure/volume that you need to regulate them down...some can be run without(low pressure units). It was recommended to me to wire up my fuel pump with a fuse and a relay. I hope that helps some.

Re: Electric Fuel Pump Advice

Thanks for your help. I have been told running one of these electrics on the street for extended periods will burn them up. This is really what i am wondering if it is true. Thanks

Re: Electric Fuel Pump Advice

lots of vehicles out there run electric pumps, both factory and aftermarket. The type and pressure the pumps puts out determines if a regulator is needed. Also as stated it should have some type of protection from surges ( fuse or breaker). Electric pumps are better at "pushing" fuel than sucking it, so you'll want to locate it as close to the tank as possible. Bottom line - buy a decent brand pump and you'll be happy whether it's electric or mechanical in the case of a weekend street cruiser.

Re: Electric Fuel Pump Advice

Also be sure to wire the pump using a relay to be sure it gets constant 12v power. It will burn up in short order if you don't.

Re: Electric Fuel Pump Advice

Like already mentioned buy good quality parts. Get a regulator with a return line back to the tank. They are little more money but worth every penny. It will keep fresh fuel circulating through the pump keeping the pump cooler and fuel pressure more consistent.

Re: Electric Fuel Pump Advice

Why would you want to go with an electric pump? Typically you go electric if your going EFI or running some big hp numbers. No reason to add all the effort and expense for your combo.

A good electric pump with the correct setup wont burn up.

Re: Electric Fuel Pump Advice

Thanks for all the input. I guess i am wondering about an electric because of running 2 carbs. Will a stock oem style mechanical pumps work ok with 2 Holley 450's?
