Fix for fuel tanks with soft & tacky residue

It has been brought to our attention that there are some fuel tanks in the field that have a soft, tacky interior. After talking with the manufacturer of the tanks we have determined that rinsing ALL tanks with lacquer thinner will eliminate the tacky residue.  

HOW TO RINSE YOUR TANKS:

For tanks set in wings:
1) Fill the tanks with lacquer thinner (9 Gal. tanks fill with 1/2 gal. - 1 gal.) (13 gal. tanks fill with 1-2 gal.)
2) MAKE SURE TANKS ARE VENTED!
3) Rock the airplane for 3-5 minutes to be sure the thinner contacts all inside surfaces. (Decreasing tire pressure will facilitate the rocking process)
4) Drain completely, putting a portion of the fluid into a transparent container to determine clarity. This will look yellow if the interior walls have not completely cured.
5) Repeat this process until thinner is clear. (Our experience with this, had it washed clear by the third rinse, but could vary from tank to tank).
6) Let stand overnight and test walls with your finger. They should now be hardened and impervious to gasoline.

For tanks not set in wings:
1) Follow the above procedures using only about a quart of thinner.
2) Shake the tank by hand.

To determine the extent of the problem, please notify me at Just Aircraft of the following:
1) If you have found soft, sticky tanks
2) The above procedures did not resolve the problem (NOTIFY ME IMMEDIATELY).

Thank you for your patience and we apologize for any inconvenience this may have caused you.
