BobT-47P15 Posted April 7, 2009 Report Share Posted April 7, 2009 Borrowed from the HAMB. From a thread of elect pumps..... The ones made by Facet and Purolater are good quality and I have used them since the mid 70's with good luck. Like everything these days they have been knocked off by countries with no ethics and there are some crappy copies out there. These were actually used by Mazda back in the 70's as the stock pump and they were a good piece. Buy the name brand and you have good luck. They put out from 1.5-4.5 psi. the nice thing is the size and they seem OK in most positions. __________________ Link to the post: http://www.jalopyjournal.com/forum/showthread.php?t=317642 Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted April 7, 2009 Report Share Posted April 7, 2009 My guess is that is a 12 volt only pump. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted April 7, 2009 Report Share Posted April 7, 2009 12 volt..polarity must be maintained..the pump should be iso-mounted as it bangs like a rapper if not...I have run these since 1984 and is my choice of pump first and foremost...original was by Fawcett but has since been sold I think and names like Purlator and Carter has their names on them today.

David Strieb Posted April 8, 2009 Report Share Posted April 8, 2009 got this at carquest, I think it's a carter. E84259 6 volt +/- ground. Been on my '36 Chrysler for 2 yrs w/no problems. Quote Link to comment Share on other sites More sharing options...
David Strieb Posted April 8, 2009 Report Share Posted April 8, 2009 Was gonna say that it's a good idea to use a oil pressure switch to work in conjunction with an electric fuel pump so that the fuel pump will only work when there is oil pressure.

grey beard Posted April 8, 2009 Report Share Posted April 8, 2009 David, How does one start an engine whose fuel is supplied by an electric fuel pump that must first have oil pressure to operate? Seems to me like you'd wait a long time for fuel to reach the carb, what? Quote Link to comment Share on other sites More sharing options...

Or the pump could also be tied to the starter button circuit assuming the vehicle has such a circuit. Quote Link to comment Share on other sites More sharing options...

Seems to me like you'd wait a long time for fuel to reach the carb, what? Turning the engine over with the starter creates enough oil pressure to activate the switch and send power to the fuel pump, plus the carb stores enough gas to start the engine. The safty factor is this: if you get in an accident and your engine stalls, without this switch, your fuel pump would still be pumping gas as long as there is power to it. With a broken fuel line, you could very well become a "crispy critter" The switch installs with a "T" fitting where the oil line comes out of the engine block and goes to the oil pressure gauge in the dash. I don't have a part # handy, but I believe new cars have used this for some time now. Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted April 8, 2009 Report Share Posted April 8, 2009 If it works well for you that is good. That setup would not work well in my 48 Plymouth. If I do not start my car for an extended period of time my carburetors are dry from evaporation. And it takes my engine a few moments to build oil pressure. I believe new cars have a mechanical switch that opens upon impact (a crash) and cuts power to the electric fuel pump. I am not aware of any that rely on oil pressure to run the fuel pump. In my modern fuel injected vehicles the fuel pump comes on as soon as I turn the key on. The only reason I would install an electric fuel pump in my Plymouth would be to prime the carburetors for a quicker start after an extended shut down period. As of now my mechanical pump works well.

T120 Posted April 8, 2009 Report Share Posted April 8, 2009 I've installed an electric fuel pump in the past-6 volt pos. gnd.-It was mounted on the frame and switched.It was in series with the mechanical pump and used only to prime the carb for starting after a period of time when the car hadn't been started.In my opinion this is the only advantage to installing an electric fuel pump.In both cases where I've had a mechanical pump fail on a trip they were both leaking gas.I think carrying a spare mechanical pump is a better idea.Also fuel pressure to the carb should be checked if installing an electric fuel pump to ensure it isn't too high - could cause a flooding problem.

grey beard Posted April 9, 2009 Report Share Posted April 9, 2009 I'm also using the Carter 6-volt pump. It's the nicest, heavy-duty fuel pump I've found on the market, AND it was reasonable. I found it by accident - went to NAPA and ordered it blind from their catalog. When it came in and I saw it was a Carter, I was delighted. Now I'm looking for a good heavy-duty base-mounted spin-on fuel filter to put between this nice Carter pump and the tank. Oughta' last till the cows come home, and I haven't seen them critters for a spell . . . . . . NAPA part number is P-4259 - $60.49 two weeks ago, here in Pennsyltucky.
