2015 Tahoe LT 185K, dry Texas climate, no rust whatsoever. Strong fuel smell on driver's side as well as inside the cabin when driving. No smell under hood or inside gas cap compartment. Slow start after sitting overnight. No codes. no visible leaks. Replaced Vapor Canister Vent Valve (GM 23481275) but did not resolve smell. Any suggestions? Thanks in advance!
Gas smell inside and out SOLVED!

Seems like some owners have had to replace the Fuel Feed Hose (GM #84200271) because the plastic hose rubs against the undercarriage and causes a pinhole leak. Anyone experienced this problem? Smell is strong around tank.

Have you crawled up underneath and put your hand on top of the fuel tank yet? Especially when running?

That’s exactly what happened to my 2015 a couple of months ago. No drips, but residue on the tank. Hard to start after sitting a few hours.
While it is running, can you get something like a bore scope camera up there or a mirror and light? Don't want to mess around and guess too much with a fuel leak.
Problem solved! It was the Fuel Feed Hose and it was the result of rubbing against the undercarriage. The GM replacement part has a braided cover over the plastic tube so the redesign should prevent the problem from occurring again. Hope this helps someone else.
Please go back to start of the thread and edit the thread title to say SOLVED and then other members will be more likely to read the thread if they have the same problem.
