Hi all I finally got around to chasing a fuel smell from the front RH side of my 987.1 Cayman (RHS drive). After pulling out the RH wheel liner, I found traces of fuel coming down the side of the tank from the filler inlet. I assume I either have a crack where the filler meets the tank, or there is something wrong with the connection between the filler tube and the tank (there was some fuel in the foam ring at the bottom of the filler tube, not sure if that is relevant) I am willing to throw as much epoxy as I can get my hands on at the filler neck, rather than pay for a new fuel tank, but it is really hard to access this area, I could only get the product on the RHS side of the filler tube. Is there an easier way to access this location rather than just through the wheel well? It didn't look there would be any better access from underneath? Open to any suggestions

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Pull it apart and replace gaskets, don’t do anything drastic, the prices shown are US$
Thank you for the advice. I will get parts 16 & 17 and hopefully that does the trick
Just a follow up in case anyone stumbles across this in the future. The parts were $46 from the Porsche dealership (bargain), although I am not convinced that the foam gasket does all that much, as even the new one is a very loose fit, up against the neck of the fuel tank. Having said that, it forced me to remove the fuel filler neck which is surprisingly easier than it looks. With that out of the way, I was able to get some good access to all of the seam around the fuel filler neck on the tank, which meant I got some good layers of fuel resistant epoxy all around it. For now, this appears to have fixed the fuel leakage, with no more fuel smells in the cabin or near the front RH wheel. Not sure how long it will last, but happy with it so far.
Fuel leaks can result in fire/ explosions. That is best left to mechanic who knows what he is doing.

Do you remember how you managed to change it by any chance, Looking at replacing mine and not sure if i should start digging in the wheel well or take the front boot apart.
