The left wing's fuel sending unit had a small leak around the screws when the tank was pressure-tested. I decided to remove the rubber gaskets that had been used under the sending units. The fuel sending units were removed and the rubber gaskets were removed. The surfaces were cleaned up with MEK. Car wax was applied to the fuel tank area around the sending unit holes to help remove the sending units, if necessary.
Proseal was mixed and applied directly to the fuel sending unit. Screws were dipped in Proseal and then screwed into the sending units. Proseal was applied around the edge of the sending units.
