Missed that, I'm not aware of fuel systems vapor locking while running, it's
possible after restarting on a hot day and no cool down, especially at my
altitude and the heat we get but I think he is from Michigan so the altitude
part is not applicable. The constant pressure should keep the vapor lock from
occuring. It's also possible that the blockage could occur after the inline
fuel pressure gauge. If the last thing the fuel passes through before being
split to the carbs is the pressure regulator, I would still look into that
item.
