How To Run An EFI Fuel Pump On A Carbureted Engine

Why run an EFI-style fuel pump on an engine with a carburetor? There are a whole host of reasons, including cooler fuel temperatures, more stable fuel pressure, longer pump life, and the ability to handle boost referencing, if you need it. And if you do decide to convert to EFI later on, your fuel system will be ready!

Good information thanks for sharing

[@CaptoCapri]

Why is it that I can't find a single video about regulators where the person actually addresses one of the most important things to consider... the sizing of the return line??

[@Macnificent78_]

What fuel pump do you recommend on a 383 stroker holley sniper roughly 500 + hp???

[@crazyhorseracing6130]

I just purchased a Holley 12-159 and I'm going to be running a carburetor. What regulator do you recommend for this set up. Also what size fuel line and return do you recommend?? Thanks for the videos!!

No you do not want to deadhead the fuel to the carb, you will burn up the electric fuel pump since it uses the fuel as coolant. Therefore you need a return line so the fuel continues to flow thru the pump at all times. And there is no gain by going to an efi pump, if you set up a 5 to 7 psi pump correctly. Just use Napa fuel filter 3041 for 3/8 line or 3040 for 5/16 line and a good 5 to 7 psi pump.

I installed a Holley red pump on my 1970 F250 about 6 years ago against the warnings from a few co- workers that it would fail. Well it did after only about a month. Very disappointed as I had used that same pump in the 90's with never a problem....anybody else have the same or similar results using the red pump?

Does the regulator need to be up front by the carburetor or is it ok putting towards the the fuel tank and running a shorter return line back to tank and would the 6psi regulated pressure pushing fuel to carb still be able to solve a vapor lock problem?????

I have a 1990 Corvette with the L98 TPI motor. I want to go with a carburetor. So my question is could I use the 12-880 and just change the spring to go from 40 psi to 7 psi ?

Interesting. Thanks

First thingI have a never bin started rebuild Olds 350. Will be putting in a Holley EFI, but having trouble figuring out the type of fuel pump and regulator needed, please some advice. Secondly does the engine need to have bin running before installing an EFI?

[@calisippweezy2848]

With the electrical fuel pump, do I supposed to bypass the manual pump?

[@ozielmadrigal9374]

What regulator kit(part #) would be best suited for my carburetor application ?

[@tonysingleton8340]

Having the bypass regulator after the carb, instead of before it, is the better way to go.

[@arenkun2811]

I don't understand though? What if the carb has no return on it? I get you can t of the feed but what is the benefit of doing it after the carb instead of before? Wouldn't you want it regulated before the carb?
