Gas smell

Hi keep smelling gas around my truck when I start it in the morning or have it sitting for long take it back to the dealership. Tech could not find anything they want me to come back on Monday, Should I start familiarizing myself with my truck by searching for my self. Any advice appreciate
See this cruising the other day. Think this a true reading?

 

Any mods to the bed? Tonneau cover installed?

 

Welcome to TacomaWorld!

 

Yes cover

 

Check the filler neck to the gas tank, could have been nicked or drilled into when cover was installed.

 

Just extang 2.0 no drill

 

Tank shows full. My guess is at some point you over filled your tank and got fuel in your carbon canister. Do you full past the first click filling up? This thought is supported by it doing when it sits our in the morning. This is the expansion cycle of the diurnal cycle the carbon canister was designed to stop.

 

Never over fill smell even when half empty . Every startup

 

tighten up the gas cap,

 

Fellow Tacoma newbie, I've noticed an occasional smell after fill up. It seems to go away in my case after the first run. I have crawled around to see if I can find the source and come up empty. There are some threads on here about pinched lines from the factory, but there's no smell under the truck or in engine compartment. I've come to think the smell might be on me. I went from a 2005 F150 to a '17 Tacoma and I think I was so used to smelling the road with the ford, that in the tightly sealed, cabin filtered Tacoma I am just noticing the bit of smell I take with me. It also seemed to go away for the most part after I installed Weathertech floor mats, which kinda supports my theory that I was dragging the smell in with me.
I tried to find the thread I saw for you and failed...I am still new, however if no-one has told you wording your search "tacoma world..." and using the google search option is much more effective than the internal search option of your trying to avoid making a duplicate thread. If you find anything out keep us in the loop!

 

Is your lane assist on in that picture?

 

Yes always be on

 

I should have asked if it was actively engaged at that moment.
