Fuel pump problems

Question type: Maintenance & Repair

I have a 1936 chevy with a 1977 chevy 350 in it. I was
coming home and at the driveway it quit running and would
not start again . It sat for a 2 hours and then started. When
it guit the fuel filter was empty. When it started we had
replaced the mechanical pump and the filter was full. I
started to drive it and went about 500 yards before it guit.
Fuel filer was empty. It has a new line from the pump to
tank. Do not know what is in tank. Any ideas would be
great. Email is royfly2@aol.com

An old prank was to put a ping-pong ball in someone's gas tank. The fuel pump will suck it down to the pick up tube in the tank. The engine will stall and the ping-pong ball will be released because the fuel pump stops. You can then start the engine again and it'll run for a few minutes then stall again. The cycle repeats. Just a thought. It also could be vapor lock. HTH. -Jim


Agree with the vapor lock. Are you running an exhaust too close to the fuel line?
