My Dad has a 1950 Ford Custom that runs for 10 minutes then shuts off. After it cools it will start again and run for 10 minutes and shut off. He does have an electric fuel pump on it and he needs to use it pretty much all the time to start the car. Could the electric fuel pump have gone bad and it is not pumping the fuel up to the manual fuel pump? Any suggestion would be greatly appreciated. Thanks, Darla

Other things, electrical things, can fail after ten minutes. Both the coil and the condenser can work fine when cool, then fail when warm from operation. My suggestion is to do the basic test to determine if the problem is a fuel problem, or a spark problem. When the problem occurs and before it cools down, remove the air cleaner and look down into the carb while manually pumping the accelerator. Should see two squirts of fuel. If not, the problem is indeed fuel delivery. If the squirt is there, fuel is there, so move on to look for spark failure. Remove a spark plug lead and hold it near a head bolt, crank engine, should see a blue spark off the spark plug lead. if no spark, replace condenser and/or coil.

Hi Darla. Welcome to the Forum. Your Dad's problem sounds more like an ignition (weak or no spark) problem than a fuel problem. I would start the engine and then disconnect a spark plug wire and hold it near a head bolt until he sees a spark. A good spark would be from 3/8" to 1/2" and be blue. An orange or red spark is a weak spark. If the spark is weak, I would replace the coil and condenser. If the spark is good, I would check to see if the carburetor has fuel. To check for fuel in the carburetor, when the engine dies, turn off the ignition switch, remove the air cleaner and while looking down the throat of the carburetor, operate the gas pedal linkage. You should see 2 streams of fuel squirting into the carburetor. If you do not see them the problem is fuel related. Once he has determined if it is fuel or ignition related and wants more help, just reply to this post with any questions. Please let us know the results. Tom

The problem is fuel related. Last night they checked to see if there was fuel coming out of the electric pump from both ends and they also checked if there was fuel coming out at the carburetor and there was. They are at a loss of what to do next. Darla Glenn

Take the coil to an auto parts store to have it checked. It is most probably bad.

My Dad has a B5A-9350-E6V electric fuel pump in his 1950 Ford Custom. He would like to know what psi that pump is. also the pumps runs for 15 minutes but then the pump shuts off after the 15 minutes and the car dies. This is while it is idling but it has left him sitting more times than I care to count. Any suggestion? Darla Glenn

Why not eliminate the electric pump and just put a new mechanical pump on the motor? Also is there an in-line fuel filter near the pump? If so has anyone checked it? I'm having difficulty understanding why the pump would shut itself off if there is power to it?

Darla, it sounds like the electric fuel pump is defective. It runs until it overheats and then shuts down. The P/N that you posted is a vendors P/N, not a Ford P/N. I am not a fan of electric fuel pumps. They cause more problems than they fix. Tom
