Electric Fuel Pump Location
I have a 65 GTO that I have a manual fuel pump on, it is an Edelbrock Performer RPM Pump. My problem is that when the car sits for a while the gas evaporates and it takes a lot of cranking to get it to start. I already installed a check valve to keep the gas from draining back to the tank, but it hasn't completely help. So I am going to install a pusher electric pump back by the gas tank to use only for priming the line and filling the carburetor prior to starting. I am going to use the Carter P4602RV which comes with a bypass and check valve system so the manual pump doesn't have to pull through the electric pump when it is not running.
My question is where are people mounting these pumps? The only area I see where it would have enough room is on the trunk above the tank and in the axle tunnel. It would have to be offset to avoid interference with the rear pumpkin. Does anyone have a better place? It is recommended not to mount them higher than the gas tank but I really don't see anywhere else where it would work and be close to the hard gas line and clear the rear end and exhaust. Any advice would be greatly appreciated. I found the mounting instructions on line and it can be mounted up to, but not higher than, 24" above the bottom of the tank. Thanks, Dale

I have also found this pump https://www.summitracing.com/parts/atx-e8090/overview/ and was wondering if I could get away with just putting this one in without a bypass and let the mechanical pump suck through it when it is off? I know some pumps are designed different inside and don't create a problem letting fuel just pass through them. Again, I just need it to prime the carburetor when it has sat for a while and to act as a backup pump for emergencies.
Thanks, Dale

I would more inclined to mount it on the rear cross member on the front face over top the axle toward the passenger side of the car. That way you could pull out of the tank, and then a straight shot into the fuel line without having to modify fuel line.

I may end up having to do the same thing. I had the same problem when i had my 66 GTO with a Carter AFB. New car will be the same set up so..... I probably should be looking into that too. Good idea with the pass through as i would also only want the pump for refilling the carb after sitting. My body is still off the frame so this would definitely be the time to do it.

Fuel Issue
I have a Holley mounted to the tank strap for 30 + years with no issues, I can send you a picture and recently had the same problem on another 64 as you are experiencing so I added a fuel pump, well the issue was still there, had to dump gas in the carb, Took it off , rebuilt it and guess what starts with a few pumps of the pedal and I left the fuel pump there if I ever upgraded the motor it's ready. I installed a toggle switch under the dash in a factory hole, and if need be I can turn it on. If you need any pictures, just send me a email or # to text to. Hope this helps.

I'd love to help with that but i don't have my fuel tank yet and the car didn't come with one. I plan on picking my tank up at Norwalk so i don't have to pay to ship it.

Thanks Dale, I will. I've got my frame done and re assembled except for the internals to the rear axle. Unfortunately, I've not been able to work on mine since September, due to working overtime and a side project 66 Lincoln Continental that i'm refreshing. I took that on to help pay for my project, and things at work exploded instead of slowing down as forecast. Lots of background going on for mine though. Block at machine shop. Block has been tanked, bored and align bored. I have all of my engine internals except for pistons and rings. Heads at SD Performance. Got trans built and sitting on work bench. Got paint, tires, wheels, all the soft interior, radiator is out for recore, brake booster out for rebuild and dash pad out at Just Dashes. Just got distributor back from being recurved. So while work has kept me from working on the car, it's definitely helped pay for it. It's looking like i won't get to do much this summer either, but i'm hoping to finish my portion of the body work and get it to the painter this fall or early winter. Your car came out phenomenal, and your efforts really show. The average person just doesn't realize how much goes into bringing one of these back. Hopefully, I'll see yours in person one day at a show somewhere.

I have a Holley pump between the rear of the tank and rear most crossmember and its really tight. I chose that spot because I installed a sump in the bottom of my original tank. The closer you can get to the tank the better. And it's pretty noisy so that's another thing to consider.

Can you post up a picture of this pump? Everything I am seeing pretaining to an "Edelbrock Performer RPM Pump" comes up as a mechanical pump and there is only 1 way to mount those.

Thanks for the recommendation, I will check that area out and see if there is enough room. I have thought of putting it on the front of the crossmember that runs in front of the axle but that would be a long distance for the pump to pull fuel. The pump should be here today so I should be able to get under the car with it and see where it will actually fit. Thanks, Dale

Okay, now I got you. That Carter pump is a good pump and used by many with antique cars to combat vapor-lock. It will work for what you are after but it does not seem like "drain back" is your issue unless the car sits for months. If the car sits for months at a time then evaporation could be your problem but that would also come with carb problems as the fuel keeps drying, so do seals and gaskets. It would seem to me that your problem is more carb related than anything else. What fuel do you use? Pump gas? Ethanol free pump gas? Race fuel?
By the way, that style Carter pump can pretty much be mounted anywhere. |

Did you ever look into the choke setting, both initial and pull-off? All my stock Pontiacs always started just fine even after sitting for a couple of months. It was only if they sat for a year or more that I either had to do the 'ol crank 'n pump or pour a shot glass of gas down the carb.
