Hi,

I have a vapor lock issue with my Firebird 67 400. I have just a simple braided line from the pump to the carb with AN fittings (see attached pictures).

Is it best to add a return line just at the output of the mechanical pump runing under front engine or to split the fuel line just before the q-jet inlet ? (or change the pump to add one with a separated return output line ?)

Any other options are welcome ! Thanks to post pictures of your setup !

Pierre
