A big cause of hot fuel issues is the exhaust crossover under the
carburetor. Blocking that crossover was the single biggest improvement for
hot fuel on my coach. The problem is really aggravated if one of your
mufflers has a problem - forces hot exhaust to balance via the intake path
- really hot.
