Strong Smell of Gas In Vehicle

[thindart1990]

Need some advice on a strong smell of gas in the vehicle after working it pretty good on the trails. i have searched youtube and ih8mud and found that it could be caused from vapor lock. CEL diagnostic is showing potential EVAP issues. I turned it off for about an hour and it seemed to cure the smell. But curious if anyone else has had this issue and what resolved it? I have found some potential things to look at updating are:

1. EVAP lines
2. New Charcoal canister

Haven't tried either, just looking for some input on other's experiences and what I should start digging into first.

DANGEROUS GAS PRESSURE BUILD UP IN GAS TANK!
Why?
What's going on?
How can we fix this?

Since first posting this thread. I've corrected many boiling fuel. By working in this order:

1. Coolant system if first on the list, must be operating as designed. Which radiator fins cleaning is key.
2. Engine tune, so it's running at peak, is a must.
3. EVAP system must be work as design. Which I find all 03-05 and 70% of the 98-02 boiling fuel, have bad Charcoal canister.
4. Built rigs, especially with belly pans. Are directing heat onto: fuel & EVAP line and onto fuel...

Thanks for this! Sounds like first step will be the charcoal canister. I’ll be addressing that asap.

Have you tried changing your gas cap? Much cheaper place to start, especially if it’s not OEM.
