1969 corvette 3x2 vapour lock
1969 corvette does not have a return line on the fuel pump. Float level is a bit low just under site hole, shake the car fuel will come out . I think newer vettes were vented at fuel pump Thankyou

These carbs where restored about a year a go saw some crap when I took out the jets. Iam going to soak the carb in cleaner and blow it out Iam not convinced that was the problem I will reajust the carb maybe richen the mixture screws I read some where the fuel pump may be the problem but you can see fuel in the carb when pumping the throttle maybe the fuel is boiling in the carb maybe an electric pump high pressure will work I would hate to change over thankyou
