Installing an electric fuel pump in 67

[sburkey1967]

Second question of the day. I have relocated my battery to the trunk and nothing is wired up yet. the stock wiring harness is still intact in the car, but everything is currently loose as I just put it back in place now that the paint and body work is all done.

The car has a 351W in it now and it came with the need for an electric fuel pump which I have. I have zero experience on how and where to mount these. Do they need to be close to the gas tank, middle, near the front.....????? No idea.

Anybody ever wire up one of these before. Looks pretty basic, but I am definitely not a wiring guy if you couldn't tell.

Any input as always, is GREATLY appreciated as I am looking to get this sucker done!! Thanks.

mount it near the tank. Mine is wired off a switch that gets power from the hot side of the ignition key.Wire the pump to a relay with the power from coming from the ignition, with a 10 ga wire going to pump.I ususally put a fuse before the realy and after just in case.

Has anyone done an intank fuel pump setup to run with a carb? My carter has been getting on my nerves at idle.

good info

I will definitely try that, thanks for the information!!!

What's in that 351 that you feel the "need" for an electric pump ? Unless it's EFI or you're going to spray it, the stock mech pump is plenty for 99% of applications, even dual and triple carbs.

I need it

because I have a serpentine belt front end on the engine and when I mounted the power steering pump, there was no way the fuel pump would fit. So I "needed" to switch to the electric and just put a blank off on the engine.
I would rather have stuck with the manual.

I have a serpentine setup on a 5.0 with a mechanical fuel pump and it fits just fine. I have a hard time believing that a mechanical pump wouldn't also fit on a 351w. Does your timing cover have the provision to put a mechanical fuel pump in it ?

 

[sburkey1967]

not sure if it does...

but at this point I wouldn't change it if it did. You can see by the above photo it is pretty tight and I definitely don't want to take it all back apart again. lol

Looks like an Explorer setup, I can see now your reason. Mount the pump as close to and below the tank as you can. Electrics are made to push fuel, not pull it. Make sure you run a regulator too and it wouldn't be a bad idea to source an emergency impact switch off an EFI car to wire in the system.

mount it as close to the tank and as low as possible, lower than the outlet if possible. its also a good idea to install an inertia switch so in case of an accident it shuts off the fuel pump.

 

[sburkey1967]

thanks for the info, I will look into the regulator and shutoff deal, I don't have any of that yet.

Also put a pre-pump filter in....

Ditto, I also run one before the carb as well.

thanks guys!

All good advice, but I would add an oil pressure switch into the fuel pump circuit. The oil switch is just cheap insurance, and easy to install.

This is a great idea but I've never seen a write up on it. I know some desiels use this. Got a link ?

I'll take some pictures of mine tonight and post them.

Mount it on rubber, or run a small return line. Either will quiet it down, the return line helping the most.

But then you need a regulator (for the return line).

My warlbro 255lph pump came with a mounting kit. It had rubber coated brackets and a foam rubber sleve that went over the pump body. The pump is nice and quiet and you can't hear it at all while the car is running. The pump with install kit was an extra $10 on ebay and worth every penny IMO.
