Homebuilt aircraft have been making fiberglass tanks for years. Are we talking about the same "epoxy"

The RV/Epoxy would be for the nuts through the tank to hold the top plate. I want the top plate to be removable for service WHEN the pump fails ... and it will.

The main reason for going through the tank(using purpose designed through tank fittings) is to make it easier to service the tank & pump. Gets them out of the way and no need to disconnect when opening the tank.

Nut see the next post ....
