360 not wanting to start when warm

I have a 360 in my jeep. It usually starts fine the first time but if you let it idle for like 10 minutes, cut it off, and try to start it again it goes " whomp.....whomp.....whomp...then it will fire or start to turn over easily or it will keep going whomp. I just changes my alternator because me last one went out and was squealing and not charging. Anyways the longer you let it cool the more turns you will get, when trying to satrt, before it starts to go whomp..whomp..whomp again! Ask me any questions you need to kno about my jeep and i can tell you. Thanks

Do you have the gas filter in right side up? It sits level and the center outlet goes to the carb and the 'top' outlet goes to the return line so when you shut it down hot, the vapor created in the line blows back to the tank off the top of the filter rather than vaporlocking the gas line.

Fuel filter location

The fuel filter should be right before the carb. Trace your fuel line from the fuel pump. I have a 258 so the configuration may be a little different. Mine looks like a small barrell with one port on the fuel pump side and 2 facing the carb. Mine is 2 different sizes so don't make my mistake and assume they are the same when buying fuel line.

I posted a pic- The filter is in the lower left hand corner. It may not be turned exacty right so orient it like Mike suggested (flat with return line on top)
