How to test fuel pump on '54 Savoy

[Go Fleiter]

I was definitely bored by my Vapor Lock problems and solved them with a shunt electrical Gas Pump. It is fixed with tube wyes and hoses plus clamps. See sketch. Pressure regulator would be put into the shunt line behind the pump.
I put a toggle normally open switch, as I only use it while starting. 12 V pump was OK? with 6 V for my pupose, very cheap.

There are security electronic devices shuting the e-pump off,? to avoid gas spilling in case of an accident , but I didn?t find one for 6 V. If not, in an accident: the pump will continue to spill gas on the road.

The car will not be eligible when judged, unless You unclamp all back to the original setup.

Chris-

If you do decide to go with an electric fuel pump, Summit Racing (they have a website) has a 6 volt (positive or negative) rotary vane pump for about a hundred bucks. Since it is rotary vane, you shouldn't have to worry about modern fuel, which might cause problems with a bellows pump. It puts out 6 1/2 psi, so you would want an adjustable fuel pressure regulator between the pump and the carb (they also sell regulators). You would probably also want a fuel filter between the tank and the pump.

Assuming the cam lobe is worn, what, if anything can be done without tearing down the motor?  Is the only thing left to add an electric fuel pump?

disconnect the feul line at the carb, discinnect the coil wire at the coil.  direct teh fuel flow into a suitable container, have some one engage the starter while you count fuel pulses.  12 pulses should give you 8 to 12 ounces of gas in tht e container.

Have you checked for an obstruction in the float check valve.  On assure that your float level is correct.

If You really want to see: disconnect the gas hose from (COLD!) carb and hold it in a big jar. Someone turning the starter will show You what the pump delivers.

I've started having issues with the fuel system on the old Savoy.? I have to prime the carb with gas to get it started after sitting several hours or days.? We thought perhaps it was a clog in the tank or lines, but the lines are not blocked nor are the vent lines.? The fuel comes out of the tank with no issue.

We are starting to suspect the fuel pump is not delivering enough.? How can I test it for proper operation?? If it's fine, then I'm wondering if the lobe on the cam that contacts the arm of the pump is worn.? How do I overcome that?? Is there a way to modify the pump arm so that there is enough contact?

Suggestions welcome, Chris.

Sounds like a carburetor problem. If the car runs ok after you prime it and it drives ok, it is not the fuel pump so testing the pump would be unnecessary. After it sits a couple of days are you pushing the gas pedal to give it some fuel as you are trying to start it?
