Electric fuel pump for carbed 302 questions
 

I may just decide to use an electric fuel pump instead of my mechanical one when switching my efi over to a carb, so my questions are how easy is it to wire up an in line fuel pump? (I am not a wiring genius). Do I have to mount it under the car, or can I put it in the engine bay? is the holley red a good pump? Will I need a regulator?

buy a pump with a wiring kit and relay.. best and only way to go. You should mount it under the car near the the tank, it won't work right if it far away from the tank. If its to far it will starv and stress on pulling the fuel as where the closer it is the quicker it will prime. The holleys are great. I would use a regulator to ensure you don't blow the carb to bits.

You'll also need to drop your fuel tank.

You must replace the fuel pickup on top of the gas tank with a purpose built pickup that does not include an in-tank pump. You may want to replace the fuel line too.

You can get a inline electric pump for 25-35 $ with low pressure. I run one on my old Bronco with no problems.

Electric pumps are designed to push fuel, not pull fuel. So do what 88 said about mounting it as close to the tank as possible.

Maybe others' experience differs from mine but I must say this:

DONT DO IT MAN! It's a royal pain in the *** to go electric and then try to get the pressures right. I tried EVERYTHING to get my electric pump to pump the right amount of gas and pressure and either it overpowered TWO regulators inline with too much pressure or it pumped too little at the right pressure and my carb starved and the engine stalled. Save yourself a ton of trouble and get the FMS timing chain cover with the hole, an 85 eccentric for your cam and the FMS mechanical pump. I mean you are making the engine "mechanical" instead of "electronic" with a carb so go the whole way and make the fuel delivery mechanical too. With a mechanical pump, no regulators, no worries no nothing, it pumps based on engine rpm and it is constant and low pressure. Easy as pie. Plus no wiring.

Just my thoughts and reflections on my own electric pump/carb nightmares.

As for the tank, drop that sucker, pull the pump out, unscrew the pump motor itself and then take the pump top with the two metal tubes and slip a length of rubber fuel line slightly longer than necessary to reach the bottom of the tank. This way, it turns sideways when it reaches bottom. Then reinstall and you can use your stock fittings and steel fuelline all the way to the front of the car. I've had this setup 2 years and counting and I have yet to have a problem.

I guess I confused everyone a little bit. The car was an 84, and it had the original engine till I dropped a rod, so it already has the carbed fuel pickup in the tank. (I am just switching an 88 motor to a carb). I think I am just going to go the electric route right now to see how that works, I just picked up a Holley red fuel pump off of ebay for $35.00 (remanufactured). The ad in the summitt catalog says that it does not require a fuel regulator.
