Fuel smell when cabin heater is turn-on

Anybody notice fuel smell while cabin heater is "on." In the past 3 days I've notices a faint smell of fuel when the heater is turn on, temps have been in the 30's in high desert (CA) during the day. My oldest daughter smelled much more yesterday while seating in the back seat. Checked fuel supply lines and fuel rails in the engine compartment.Truck has 3000 miles,2018 TRD sport. Thank You

 

2018? Take it to the Dealership and get everything documented in writing. Not only is this a warranty issue...this is a safety issue.

 

Already called them and made an appointment, thank you for the replys

 

Agree with getting it to the dealer. Did you by chance over fill the tank? Get those couple of extra clicks at the pump? Could be you flooded the carbon canister in the evap system. You would smell it the most during the warmest party of the day if this was the case. Even if warm is still very cold. Smell would go away at night. Or if you filled it at the coldest point it might do it for days. I deal with epa systems on boats and this happens regularly.

 

This has happened on some vehicles in the past, but I "topped" my Son's 2018 OR every fill-up before giving it to him and he still does...no smell.
