69 Dart Hard to Start When Hot, Starts Fine Cold. Vapor Lock?

Hey guys, lurker here turned member today.

My 69 Dart Slant 6 runs like a top, but has a VERY hard time starting when hot (lots of cranks). I heard it could be fuel vapor lock based on what I've read on these forums. Something about the fuel line being close to the exhaust manifold.

Is this what's happening based on this pic? If so, what is the fix?
A/C car, has been removed and choke functions correctly.
TIA !
