This only happens while driving, and I wasn't really concerned about it until now, but when driving my truck for awhile I notice the smell of fuel in the cab, it gets rather bad after driving for a while (enough to give me a headache). So my question is: Is what i'm smelling unburnt fuel from a misfire? or a fuel leak, maybe i should replace my fuel filter?

 

have you looked for any leaks under the hood or under the truck?

 

I replaced all the rubber lines on my truck and there was a lot of dry rot.

 

i would also wonder if the charcoal canister is missing. i know mine is and when i have a fairly full tank you can smell gas.

 

no but i will tomorrow, i can only smell the gas after it has ran for a while and i have never spotted any marks on the ground that would indicate a leak, i will have to look for the charcoal canister as well.

 

if you have one you will notice it on the passenger side wheel well.

 

Did you ever find your gas smell issue? I'm having the same problem.

 

well I never found out why I was smelling gas. That is mostly because I crashed and haven't driven it much since. I slid on ice and 360ed into a speed limit sign one icy morning on the way to school Hit right dead center on the driver's door, bent the floor up, put a nice kink in my dual exhaust, and shifted the whole cab to the right. Still runs like a top though! I used her to pull a friend out of some mud. Right now though she is sitting in the backyard with a tarp over her. Got a new 1999 dakota for my daily now.

 

Mine smells only in the am for a min or so. It smells only when i am stopped and truck is a 1988 with a 3.9

 

Found out mine was a leak in the fuel pump. Only found it her I left the motor running and looked under the hood.
