Electric fuel pump location on 1965 coupe
As it turned out, the second pump DID NOT fail but t was rather the ignition condenser which in turn took out the ORIGINAL 59 year old coil
I know these pumps are designed to push not pull. My mechanic says there is no space under the car at the tank to locate it safely and mounted it at the right rear of the engine compartment on the frame rail. He said this is lower than the fuel tank outlet so it is gravity feed to the pump. However I have had 2 new pumps fail in the last two weeks. The second one was a Carter and don’t recall the maker of the 1st one. Any suggestions from members that have had a similar problem? SEE EDIT IN BOLD ABOVE |

Wild card here, is the wiring to the pump done right? As a Vette is fiberglass you could have a ground issue! |
Pics of wife?

Your mechanic doesn't know what he's talking about and yes, you REALLY want the fuel pump as close to the gas tank as possible - this is what I installed - you have to be very careful with electric pumps - most put out too much pressure - this one is perfect:
https://www.amazon.com/GoodQbuy-Univ...6WD6SSZM&psc=1 Here is mine mounted just in front of the rear valence on a 63 coupe; you can see where the fuel tank sending unit is for reference: You can also see it in this video at 10:30 minutes in: |
I used to run 2 fuel pumps in the rear of my 68 Vette (2nd one for fuel supply for nitrous). No issues finding a mounting location. Would have to look through my old pics to find the setup. C2 and C3 were about the same in the rear
|
I had no problems finding a spot near/at the fuel tank for my electric
fuel pump. Maybe your mechanic should try another smaller pump. Good luck |

Thanks Frankie. That is what I thought but as my age increases my memory diminishes. :)

Two caveats though - if you do NOT have an oil pressure OFF switch for the pump and you should have a rollover or violent wreck the electric pump will most likely NOT stop flowing fuel (huge fire hazard) If you have a full-time electrical pump that's a big consideration.
Second, if you run the electric pump as a booster or "back up" THROUGH the mechanical pump (yes, it works) and the mechanical pump diaphragm/oil seal fails; you'll pump your crankcase full of gas and never know it because the engine generally will not stumble/quit. Not an issue if you are replacing the mechanical pump though. |

Worried about a pump run on I wired it through a on/off switch and the ignition switch. That on off switch also acted as a theft determent, but this set up was not as good as the oil pressure switch you mentioned. Hey I was just a dumb kid way back then!:D Drove it like that for 3 months then bought a better newer car! |
Dumb question; what's wrong with using a factory mechanical pump?

Maybe we could have some kind of forum function where thread starters could opt to have their threads shown in both a generation sub, and in OT, and responses would automatically show up in both threads? Just spitballing here, but that might be a way to gain membership. I see we have a bunch of n00bs who post serious questions in the generation threads, then get no traffic, and they just leave. That's wrong. We're small, but we do have a knowledge base here. Automatic cross posting would help. Is this possible with our forum software, @Rob? |

The best location is in the tank. It seems counter-intuitive but that's where modern cars put them.
