Is the tank FG or plastic?

Does any vendor have a satisfactory inspection-port kit for a
built-in
water tank in a fiberglass boat ?

If not, how is one properly fabricated/installed ?

Also, how should said built-in tanks be repaired in the event of
cracks,
fractures, etc. ?

Thank you.

Have old "food grade" polyethylene fresh water tanks on our 1966
Alberg
Odyssey 30. One does not have an inspection plate. I cut a hole
and
installed one using a neoprene ring (cut from a mouse pad) for a
gasket
but don't feel confident that it will be a 100% seal.

Was wondering if plain old silicone would be OK to use? Will it
contaminate the water? Any other suggestions? Cork gasket with
rubber
cement?


Also --- I repaired a few small leaks by heating the tank area
with a
heat gun, then using a hot glue gun to "weld" over the crack. This
seems to have worked for the time being, but, once again, I'm
after the
"mil spec" method of repairing this material. Anyone know?


Thanks for any suggestions.
