Fuel leak question
I have been fighting a problem for a while and need someone's help. I have 48 IDAs on a big block with the 10 deg canted intake. Whenever I stop the car after a drive, the heat seems to percolate the fuel and I get dripping out of the accelerator pump jet. It collects in the throat and eventually leaks out of the throttle shaft onto the manifold.
I have a return line on the fuel so it should be immediately dropping pressure when the car is turned off and I have the phenolic gaskets under the carbs.
Any suggestions? Has anyone else seen this problem and can you explain it to me and the solution???
Very frustrated!
Thanks.
