I recently purchased a 2017 Fatboy for the wife that had a huge dent in the tank from another bike falling into it. We ordered a paint matched replacement and waited for it to arrive. The dealership got the tank in and replaced it but said Harley required a replacement gas cap as changes had been made to the filler neck on the new tanks. We opted to go with the Willie G Skulls cap and fuel gauge instead of the stock cap as it's the running theme on her bike. Since we brought it home we have had very strong gas fumes in the garage for 2 days now. I find no obvious source of a leak anywhere, all is dry but the fumes persist and I am more than concerned for sure. Anyone else experience this situation? I bought and added an additional O-Ring on the gas cap in an attempt to help it seal better to no avail with respects to the fumes. Any thoughts or solutions out there?
