10. Repair of O-Rings and Rubber Seals__________________________________
A. General
(1)
Leaks can occur around plumbing fittings that you can remove, primary tension bolts, tank access doors and fuel system components that go through the fuel tank surfaces. These components are sealed by O-rings or by rubber seals. Replace the O-rings or rubber seals when they are damaged or have fuel leaks. You must apply the alodine layer to all surfaces of the tank structure that are damaged before you install new O-rings or rubber seals.

O-rings are used to seal these types of components:
(a)
Plumbing fittings that you can remove
(b)
Primary tension bolts
