I smell gas!

my sons 1988 jeep cherokee smell of gas when he turns on the heater.anyone ever heard of this?

Is it throttle body, or multiport injection? And what engine?

this is a 4.0liter with multi port injection.

Check the fuel injector seals.

The wife’s 91 had the injector seals leak, and man did it stink!
