My trip to Oshkosh was the first time N544WB was outside overnight when it rained.
No water in the left tank, but water in the right tank when sumped. I assume that is indicative of a leaking fuel cap on the right side. Because this cap leaks fuel when lineman ignore my request to leave some expansion volume in the tank, I also presume that the cap is leaking around the stem.
The aircraft was completed in 1997 and has the black o-ring. Looking at the Van's catalog, it appears that this cap has been superceded by a cap that uses a brown o-ring, that service parts are not available for the older cap and that the older and newer style caps are not interchangeable. Am I correct that I need to replace the entire cap with the newer model?
Confirmation of the above from knowledgeable individuals is welcome. Thanks in advance,
