A follow up to my original problem. This winter had the truck in the shop to fix a bunch of items and look at the gas smell. They noticed the tank appeared to have some pinholes so we replaced the tank and some of the lines. Been leaving it at work to do some work on the weekends. Guys will pull it out of the shop in the am, to put in the lot and they say the interior always smells like gas. I can smell it a little but my nose isn't the best. Once you're in it an driving you don't smell the gas anymore. Just seems to be when it sits. You don't smell any gas when walking up to the truck, when its in the shop. Just inside of it.
Pulled the passenger seat and took the tank cover off. Also unscrewed the vapor separator from the bracket. Smelled all the hoses and hose connections. Only smelled a whiff of gas at the separator hose that goes to the charcoal canister. It was clamped but was sliding on the plastic stub where it connects to the separator. I put a second clamp on it and it stopped sliding.
Also was getting a light whiff of gas on the vent line from the top of the tank to the fill hose. Bought a new piece of hose and double clamped both ends. All other connections were tight and I couldn't smell any gas at them.
Followed the 1/4" line from the separator to the charcoal canister. No canister, hard line runs along the frame, up into the engine bay, switches to about 8" of hose and it just sitting open ended. I'm guessing there was no canister when I bought the truck last year. Drove it all summer with no issues and no smell, other than when the tank was full, then would go away after 30 min of driving.
Can't figure out where the smell is coming from. I could see it coming out the end of the canister line but I would think I'd be smelling gas around the truck rather than just inside. Also, truck came with a Weber carb vs factory. 2f engine.
