Fuel Smell in Cab (1 Viewer)

[PRFISHBAR]

Hey all,
I know there's a lot of information on this issue on the forum but I'm at my whits end. I've owned my FJ62 for two years now and have been trying to get this problem solved since I bought it. Have replaced the charcoal canister, valves, vent hoses and even drilled a vent hole in the gas cap as one person suggested.
Can't fill the tank more than half way because it makes the smell intolerable. I'm hoping someone on here has been able to resolve an issue like mine and is willing to share more information as to what else I may need to look into to finally resolve this problem.
I'm to the point that selling may be an option!

There is a vent device in the rear passenger quarter panel. Access it from the inside by side removing panel in cargo area. See if all hoses are intact and not dry rotted. Make sure the vent device is working properly (google search mud about diagnostic). Also check you fuel sender/pump bulkead is bolted down and not leaking.

I've replaced all of those vent hoses behind the panel. Have not checked the fuel sending unit so will do that next. Thanks!

Check if your venting device works! Replacing hoses is half of it

What exactly do you mean by "venting device"? Can you give me more detail as to what you are referring to?
Thanks!

Ok yes, That's in good shape. Again, I replaced all the hoses going to that coming from the tank.

On my FJ60 I had a fuel/exhaust smell in the cab that was due to rust holes in the firewall that led to the area that houses the wiper motor/linkages and the "fresh" air intake for the cab. Sealed up those holes and the smell is gone.

I have the same situation as you. I'm in the process of replacing the exterior vent lines and filler hose from the tank . When you go under the truck, remove
the splash guard that covers those lines and the tank filler hose. Do you smell gas? Is the rubber grommet from the filler neck to the body intact?

Will have to check all that.
Thanks

I had this problem. I solved it by replacing the gas cap, which had a crack in the rubber seal. I have found that it is important that when you remove the cap, you notice it releasing pressure and that will confirm it seals properly. I also noticed when I pulled the inside panel that the rubber gasket that seals the neck to the quarter panel on the inside was cracked. I replaced that too and it solved my issue. And I never add additional fuel when the pump clicks off as a practice.

Thanks, Will look into that as well.
