Smell of gas in cab when I run my heater

Ok quick question... My girlfriend complains that when I turn the heat on in my truck it smells like gas. I'm not smelling it. Maybe shes crazy lol. But on the count that she may be right Anyone know what the cause may be? and of course a solution. Truck is an '06 Colorado just hit 75k. I plan on doing a tune up/ radiator flush soon, I know that may help but I'm curious if anyone may have another suggestion/know of any issues?

Simple fix: Get a new girlfriend.

Better fix: Go to the dealership or repair garage that has a "sniffer". Leaking around an injector "O" ring or fuel regulator would be likely places to start.

Leakey fuel pressure regulator. I had a fuel smell in the cab in the morning or after sitting for a few hours and it was the fuel pressure regulator. If it's dirty, clean it and check it in a week to see if it's dirty again. That's what gave it away for me.

Are you sure it is gasoline and not antifreeze she is smelling?
