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

was that an 80s van?
on that old Chrysler TBI ?
Yes I had a 1986 with the slant6
They were a bit of a mess right from dodge, it was a B250, so a 3/4 ton but it had the "light" front end which translates to the fact that I broke a lot of upper control arms I delivered a bulk route the the bigger of the 2 flyer delivery companies that meant loading the old girl with bags of flyers, on a busy week there were 4 layers and unlike ford and gms the b250 was a unit body with 5 bolt rims, the other van was a 1990 maxi van, it had the magnum v6 with a tbi, like isaid in another thread it didn't matter how cold it got I could always count on it to start right up, the 86 is the one that flooded ever single cold day, both of them got stuck if they even thought about snow
