4 fuel tank installation

[n6346m]

I know that there are several Taylorcrafts out there with the four wing tank installation and I would like to have copies of their field approvals if they don't mind sharing. I have already downloaded the one in the Technical section of this forum and would like to see how others have done it. It would also be nice to have extra "ammunition" when presenting my case to the FAA. You can e-mail me at n6346m at gmail dot com.

I don't have a 337, but it was an approved modification as part of the Swick STC for the clipwing.

I did that install on that 337. Not hard except for the routing of the fuel lines. Tim
