Title: gas smell on '94 tbi
Post by: the_legend_1981 on March 19, 2013, 05:53:07 pm

I got the truck up to around 80 yesterday on the highway and smelled a gas odor coming in through the vents. Did not notice it at 65. No visible leaks anywhere. Has anyone had similar issues?

I have a '94 K2500 that smells like that after I drive it. I never thought too much about it, I assumed it has to do with the evap canister getting old.

I suspect the same thing as Engineer.  Although there's no correlation to vehicle speed with the following, perform an inspection of the vapor canister along with all the fuel and vapor hoses all the way back to the tank(s), including the tank selector valve if present, and connections.  If the canister weighs more than about 3 lbs, it's beginning to saturate - more than ~5 lbs, replace it.
