Probably a good idea however, you still have the fuel drain to deal with.  At least on mine, it can be easily removed using a socket and wrench...
 

About five years ago after parking the Mustang II in the 1000+ hour spot at Oshkosh for several years, our trip home was interrupted by running out of fuel in one wing tank.  Quickly switching to the other and landing ASAP, we confirmed one empty wing tank.

I personally witnessed the filling of the tanks after arriving at OSH and did not see any dead grass under the wing when removing the tie downs before we left.  We also used the wings for shade numerous times during the airshows and did not notice leaks etc.

The tanks had not leaked previously and did not leak afterwards.

Apparently, someone had drained fuel from the drains unnoticed during the week.

Visually check the fuel before ANY departure.  We do now!
