Re: Vapor lock 1 and 2
George, I have seen in HQ holden 6 fuel pumps,(these are much the same as the flatheads) there was a real small hole in the top that went between the suction and delivery sides,this was I assume to vent the fuel pressure when the motor was stopped and heat soak got into the pump,these engine also used a stormier carb. Just a thought
