If the problem is the cap is now loose in the socket, the tension can be
adjusted on that cap. On the bottom of the cap is an AN365 nut. It can be
tightened slightly to make the O ring "fit better".

Subject: [LML] Re: LNC2 Fuel Caps

One of my three fuel caps appears to have an O-ring which is stiffer  
(header tank) than those on the wings. It closes ok but the tab no  
longer sits flush with the cap surface. I'm wondering whether the O-
rings which came with the original kit are now beyond their useful  
life. (not from flight time but build time)...
 From your experience, how frequently should they be swapped out in  
the field?
