I have a 1995 XJS Coupe 4.0. A few days ago, I was gassing up and there was a significant amount of water behind the fuel door. I don't think any got into the tank, but it's still a concern.

Any advice on how to prevent this? A new fuel door? A seal of some sort? One of these parts?

Thanks!

 

Did you ream out the drain? Use a small gauge wire or a pressurized can of air. Look at the diagram you provided. The drain tube will get clogged at the Y junction due to debris from the boot drain. I used a small gauge wire to clear both tubes and also the tube of the right.

 

Thank you, MHF25. I knew I was missing something obvious. I started trying to ream out the drain with some wire. I'll work some more on that this weekend, and make sure both it and the boot drain are clear.

 

The wire did it! Both drains are clear now! Thanks again, MHF25.
