No start condition after running a while
I have a guy here with a 1972 Duster slant 6 .It has the same problem. Also a 67 Barracuda same problem. It is the fuel boiling after the car is shut down. It bubbles past the needle and seat and floods the engine.
On the slant 6 we installed a return style filter from a 86 dodge pickup and hooked the return nipple to the line from the tank that goes to the charcoal canister. On the 67 we added the line from the 71 car and hooked it to the return nipple on the filter.
Ethanol fuel is the problem with all older carbureted engines. It has a lower boiling point and needs a return to relieve pressure and also keep the fuel flowing so it does not dead end at the carburetor when running.
