RE: Water in an aluminum feul tank

The "best" fuel tanks are made of monel.

Second best (only because of the limited complexity of the tank) is the roto moulded plastic.

Either has almost unlimited service life , but the cost of the mold restricts the plastic to limited sizes already in production. Multiple tanks can help "fill the space" on an existing boat..

Plastic has special mounting requirements.
