Fuel smell in cab issue

I have a 2003 double cab TRd. I am having an issue with what I think is a fuel smell in the cab. I am noticing it the most now in the winter when running the heater. There are no engine lights on, the truck runs great aside from really weak torque which I think is a whole other story. Any idea what I could look into or what to tell a mechanic or anything? We use it as a family adventure rig so my kids spend a good bit of time in it. Thanks!

 

Is the EVAP canister still on the left inner fender ?

the hose from the purge valve to the air intake might be cracked

If you had a pressure side fuel leak it would be spraying all over do you have fuel running to the ground??

 

Pretty they moved that to under the bed 01+

 

I just can`t remember what year
