Found the cause of my fuel/exhaust smell....

For the longest time I've had a problem with smelling gas/exhaust fumes in the cabin. I replaced all the rubber fuel lines months ago and the carbon canister, so the only thing left was to check the fuel check valve on the tank. It turns out that it was bad and replacing it totally got rid of the gas/exhaust fumes 100%. So if you have fumes coming into the cabin and you know your fuel lines/cabon canister are good replace the check valve.

Or retighten the clamps on the fuel lines that go into the top of the tank; they can loosen over time. I thought I had a fuel tank leak, but that did the trick.

we have smog failures in here all the time with small evap leak dtcs and it's almost always the check/shrader valves that are leaking.
