Try an insulator first.
I fought with hard starts when hot, and the typical problem of excessive cranking after sitting for several days.
I added the Edlebrock insulator type spacer and it has worked wonders.
I knew it helped when both my wife and daughter initially refused to ride in the car because of the "stinky gas" smell. They could always tell I had driven the car because they could smell gas on my clothes before adding the spacer.
Car now can sit for over a week, 1 pump and it fires right up. No problems with hot starts either.
The crappy 10% ethanol gas seems to evaporate much easier.
