How to Prevent Holley Carburetor Fuel Boiling

I need to know how to create a type of insulator or something to prevent fuel boiling in the carb. I recently had an issue where I went for a semi-long drive and when I restarted the engine hot it wouldn't start due to boiling gas leaking from the boosters and flooding the engine. I need steps on how to create something to prevent this. Thanks
Is this the first time you had this problem? Have you been driving it all summer and this was the first event like this? How old is your gas?
