Electric fuel pump installation

[Clem Clement]

I'm replacing my bad fuel line. I have a aftermarket 6Velectric pump tp install.
I understand the pump should go near the fuel tank. I have a useable hole in the frame for the installation.

1). do I need to buy a valve to control the pressure?
2) Can I use a push button to operate the pump just to get fuel to the carb? Or does it run all the time?

1) I guess it depends on your pump. I have an airtex and run without a regulator.
2) yes toggle switch under dash will work. It's also good from a safety standpoint

1. I use a toggle switch hidden under the dash to turn the pump on and off. Also acts a a theft device since it's hidden.
2. Be sure to install a fuel line shut-ff valve and a fuel filter between the gas tank and the pump. I soldered in a radiator pet cock that fits 1/4 in. fuel line. Makes changing fuel filter easy with no mess.
3. Pump doesn't have to run all the time if you are still using your OEM mechanical pump.
4. Also, install another fuel filter just before the carb inlet as an extra precaution.
5. You can buy low pressure pumps that may not require the use of a regulator.
6. Be sure to mount your pump on a rubber cushion for noise reduction. Have also been told that using rubber hoses and clamps to connect the pump lessens the noise.
Install a metal stone shield to protect the glass fuel filter from road debris. stones, etc.
Some folks don't like the glass see-thru filters as they are afraid of breakage. 20 years and I'm still good to go. Since these photos were taken I have removed that round style regulator as they are unreliable.

Clem, remember, that if you wire your pump to a "hot" feed, it will keep running in the event of a crash, causing a possible fire hazard. If you can get a copy of the July/August issue of the V-8 Times there is an article on how to wire your pump thru an oil pressure switch. If the engine stops for some reason, the pump will shut off.

Pretty much the lowest pressure electric fuel pump you can buy is 3.5 PSI, which may still be too high for float valves on 94 or 97 carbs, so a regulator is a good idea.

I mounted my pump inside the frame rail in front of the rear wheel. Had to drill a hole. I put a "service loop" of hose on both sides of the filter + pump to facilitate pump or filter replacement, and to make it possible to bypass them should they get plugged or malfunction, and a replacement not be handy.

The switch is in the dash with a momentary position to prime the carbs and an "on" position should the mechanical pump not keep up on the road. I bought an oil pressure switch to put into the "on" circuit, but haven't figured how to plumb it into that tight space at the back of the engine.

If you are running your electric pump through the mechanical pump, be sure to get a vane type pump that has no restriction against suction from the upstream mechanical pump. I am using Mr. Gasket 42S with good results, in spite of the mixed reviews. Any car parts store can get it for you.
