electric fuel pump mounting location

[Bill Monk]

69 Roadrunner, where are you guys mounting electric fuel pumps? I bought a carter pump and was under the car last night. The pump is supposed to be mounted at or below the bottom of the fuel tank. I don't see a good mounting location at or below.

A picture would be great.

Another thought, what do you guys think about running the carter with the mechanical pump? Anybody done this? pros and cons

I've run a carter pump and a mechanical pump for 30 years. If electric pump fails mechanical pump won't suck fuel through pump. Had a wire fall off pump and car stopped. They were push on connections, if they still are I'd add something to hold them on. My emergency tape job to tape wires to the pump are still on there .

I can't find a good place to mount an electric pump either, so mine are in the wrong place... above the differential & above the tank. If you're using the stock fuel pickup from the tank, the good news is that fuel is only being sucked up-hill about 6".

If you don't have exhaust out the back (I do), a better place might be inside one of the rear frame rails in the area where the tail pipes would go. Race cars tend to bolt them on near the rear bumper.

yeah, the exhaust is out the back so that limits available area

have you ever run the carter by itself? Another member said he had run the carter before and it would only keep up with demand to 5000 rpm.

No. Never had a problem it's a street car, never raced it. If it quit I'd remove it.

I ran a Carter only before & didn't notice the engine starving for fuel (no nitrous though & I probably didn't rev it to 7-grand)

I think DennisH uses one on his Coronet. If you know Dennis, you know he drives his a lot. So, I would shoot him a message.

I've been running electric pumps for 30 years with no problems, why take a chance on a mechanical pump leaking and putting gas in your oil! I have always had mine bolted to the shock crossmember, They will suck the fuel up. If you look up the spec the pumps will have a certain amount of lift, meaning how far they will suck straight up in feet.
