I pulled two on an RV-8, wings and tanks on the plane. The senders were just fine, the rubber gaskets that was on the initial build 14 years earlier started to leak. Some proseal on the orginal senders and all is well.

I removed one tank in 12 years and that was to install an inverted fuel flop tube. I had to break a paint line which messed up a pristine paint job. I totally repainted the old bird this Winter and I had the tank painted while off the wing. I put new screws with flush (or finishing) washers to secure the tank after painting. If I ever have to remove a tank again there will be no damage to the paint. (I use these washers on removable panels as well.)



These are not Tinnerman washers.

What a great idea. Where did you get these? I would like to use them on my 10 for parts that will be painted off the plane and later attached with screws.

If screws need to be removed after painted there is a paint cutter designed for screws , Aircraft Spruce has them they are about $20 and work well ,done correctly and there will be little to no damage to paint.

I have used the cutter on several occasions. If you have a so-so paint job in the first place then you might not mind the results of using a cutter. If you are proud of your paint job I doubt you would like the results. I'm not a fan.

Are these set up for 100* countersinks or do they just happen to work?
