Has anyone had a problem, with the fuel tank drain staining the top door window. What have you done to protect it.

Replace the o-ring in the drain.

Does the 4 have the same flush mount SA-18 drains as the 7? Has anyone found a pair of microscopic snap ring pliers that can get them out for the rebuild? Just had to replace a drain vs rebuild because I couldn’t get the snap ring off.
Thanks for your reply, but not what i was looking for. I need something to protect the Lexan from gas, or Lexan that gas will not stain and break. These drains leak a few drops after checking for water. Looking for someone that has had this problem, and how they solved it. Thanks

The drains on this kitfox 4 are the screw in type sold by Aircraft Spruce.
I used a fuel sample cup like this https://www.aircraftspruce.com/catal...samplercup.php
I had to hold it under the drain valve a few seconds to catch any drips after taking a sample. If the quick drain valves drip after a couple seconds I would replace them.

I use PETG for the doors. It’s fuel-proof, and easy to cut to shape.
