  • 6 Volt Eletric Fuel Pumps

    I have an inquiry to anyone who has an electric fuel pump on their car with 6 volt electric system. My question is as follows: What type of pump do you have? And where did you buy it. I would also like to know how you feel your pump performs. I have a 1949 Commander and have given up on making the mechanical pump perform in hot weather, I have all shields in place and still get a vapor lock in the (fuel pump) not just the carburetor any time its about 80 degrees. I am trying to get this car 100% for Omaha next year. This fuel pump problem is the only thing I have yet to beat. I have a Walbro bellows type on there now but it seems too delicate. I am looking for a solid state 6 volt if one exists.

    Thanks

    I solved the same problems along with the oil puking issue with a CarQuest E8011 diaphram pump on my 50 Champion.

      As I've mentioned before...

      Mounted to the back of my 6 volt, pos. ground, 6 cylinder, Conestoga is a Carter P4594 (12 volt) fuel pump. Even on 6 volts, I needed to install regulator to lower the pressure. I also just swapped the power wires to make it run correctly on the positive ground.

      All is well...works fine. Will a 12 volt item work on 6 volts of power, sure, just slower.

      Why you ask a 12 volt? The system will eventually be a 12 volt, negitive ground, 299 V-8. But I wanted to drive it untill all the swapping is completed.

        What pressure is the 12 volt pump maintaining on the 6 volt system? And what pressure should it be maintaining?

          I've got a 6 volt pump on my '51 Commander, and have installed a pressure regulator to deliver 4-5 psi. Pump is near the tank, regulator just upstream of the original pump in the engine compartment. Regulators are cheap ($10) and available at NAPA.

              60Lark,

              When I hooked it up and the regulater adjusted to 6.5 lbs from a previous car, the pump was still putting out a little over 5lbs. at 6 volts!

              For the flat head six, I adjusted it to 3.25lbs. at a no load idle
              No problems on the street or freeway.

                '49,

                Have you TRIED adding a gallon of diesel when you fill up[?] This has solved a-many a vapor-lock frustration.

                  Mike,
                  Thanks for the info, I have an electric fuel pump on my 60 Lark, that went caput last week end, I do not remember what it was rated for and I can see no numbers to tell me the rated psi. It did not have a pressure regulator installed with it. I ordered a Carter electric fuel pump from Summit that is rated for 7 PSI and I was not sure if I needed a pressure regulator or not, but just in case I also ordered a regulator that is rated for 3.5 to 8 psi. and figured I would set it at 5 psi to start with and go from there. I also am going to install an electric fuel pump on my 51 champion, just because it is much easier to start especially on cold starts.

                    Sometime in the past 2 years, The Co-Operators in TW reported on 6V fuel pumps and recommended one (I can't remember it's name or number.) I went to NAPA and ordered one, they took the number and came up with what I got. It is a rotary vane pump, with soft rubber vanes and no valves. The regular pump will pull through it, and it will overcome the evil vapor lock. It's wired so either polarity can be ground, wired through the ignition and the Fog Light switch on my '53 Commander (no fog lights). I have tried the gallon of Diesel fuel, it still vapor locks at 75 deg f., and at a flip of the switch, the electric pump overcomes the vapor lock. I run without it until problems occur, then turn it on.

                      Tom, ya know what's odd (besides me[])[?] I live where summer temps top 100 for days at a time. In fact, this year set records for continuous days with 100+ temps[xx(]. And yet I've never had to use the diesel fuel trick to alleviate vapor lock!
                      This is with my Lark ragtop and Transtar truck - both of which are V8s with mechanical fuel pumps.[:I] Why is this?
                      And here in the valley, we have to deal with fuel blended to reduce smog since we've got it worse than Los Angeles - if you can belive that!

                      Tom, I'm not saying you're not experiencing vapor-lock. I'm just incredulous that I can drive my two stock Studes on blazingly hot afternoons and never have a stumble. How could this be?[?][?]

                        Bob, I'm sure the vapor lock problem has a lot more to do with under the hood temps than ambient temps. An engine running on the hot side coupled with a design that disperses engine heat poorly was my problem. I would have kept fighting the problem in Clara but after her fourth mechanical fuel pump started pumping oil out the vent holes I gave up. As you know, I got relief from the diesel addition but now, my pressurized gas doesn't boil so readily and I don't need it.

                        The electric fuel pump I choose was a 2 wire type that allowed using it with pos ground. Also, it is rated at less than 6 lbs. pressure so I didn't have to install a regulator with it. I just wired it through an oil pressure switch and use it full time. I even wired in a primer button for awakening her after long naps.

                        It sure was nice this past weekend to be driving with a number of other Studes and not be the one that was stricken with the dreaded vapor lock problem.

                          Cool Deal, Gerry! Glad to hear Clara's been showing herself a bit. With gas over 3 bucks a gallon here, I'm thinking about dragging that Champ 6 up from out back and breathing new life into it![]

                            StudeBob, Where are the fuel pumps on your Lark and Pick'em up? The pump on my Lark VI is down at the bottom of the block, and has never missed a beat. The one on my '53 coupe is right behind the fan, at the top of the block. Vapor lock stranded me once, with my better half along for two hours in a strange (to me) town, and on the same trip, until I covered the pump with ice in South Bend. True, temps were in the 90s, but lately it's been every time I take it out, it wants to stumble. I just turn on the pump and as Mr. Gleason used to say, "Awayyyyy we go."

                              I had a 6 volt low pressure Carter ( Federal Mogal) pump on my 6 volt pos ground Kaiser. It works, just get the Auto parts store to look the # up undre Federal Mogal--Carter. It is a non diaphram pump; alcohol, etc will not age the pump's working mechanism. I ran it through the mechanical pump. Flip the electric pump on after a long non-running period and the car would start up on one try. If vapor lock hit ,flip pump on and vapor lock over.
