Fuel smell when idling

Smelling fuel when I first start up or just sitting while idling for awhile. No fuel dripping when turned off…anyone seen this before. It’s been doing this for a long time.

 

Mine seems to be running a bit rich on startup and then smooths out after warming up. Probably a choke-like function for cold starts the computer does?

 

Mine only happens when I fill the tank, but goes away at 3/4 of it.

 

I've always smelled gas, usually after fill up, or when it's hot...I thought it was the fuel evap valve, or something like that, because sometimes it would throw a P0443 code. Turned out that the tank was rusting through under the straps.

 

Fumes may be coming in because your steering shaft seal is ripped. Could be normal exhaust smell you wouldn't notice if the seal was intact.

Fortunately not their issue, 05-06 trucks switched to a plastic tank.

 

Same here. I think it just runs rich when at idle.
