"I have twin 360's in a 73 Luhrs. After running one engine for a while and then letting is sit, it is hard to start. I believe it is vapor lock. I have fram fuel filters for both engnes and an AC filter inline at the carbs.

Any ideas on how to prevent vapor lock ??"

You can not put fuel filters (fine filtration) BEFORE a fuel pump. Stack fifty of them AFTER the pump and it'll still work, but not before it! Only coarse (30 micron or greater) filtration can go before a pump or you will have vapor lock.
