Fuel Evaporating or Draining Back?
My 69 Lemans has a factory metal fuel line with no return. New rubber lines, new Spectra pick up in tank, new vented fuel cap, a rebuilt Carter 6907 fuel pump, late 70s Buick QJet built by Cliff that I used on bird years back - marine epoxy used at well plugs. When the car sits even for just an hour or two, I have to prime the carburetor to get it started. I don’t notice much of a pump shot and extended cranking doesn’t help. Once I manually prime it and get it started,! Runs well and will start up as long as it’s not left sitting. Fuel is 87 octane, 10% ethanol (MD). Any ideas on what the issue is?
