The Ford Barn - View Single Post - 1951 Ford - Not vapor lock- but something going on

Have Airtex at tank and active mechanical. Use Airtex only to prime carb. Either pump puts out 3 PSI which I understand is the maximum desirable.

Have problem like yours sometimes. Installed OE vented gas cap .... didn't make a difference. Suspect vapor lock between mechanical pump and carb due to ethenal gas.

Have recent rebuilt carb, crab, condenser and new coil.
