Moeller Below Deck Permanent Fuel Tank

These Moeller Fuel Tanks are intended for permanent installation below decks. Constructed from rotationally molded, cross-linked polyethylene plastic, allows for complex shape designs beyond conventional and metal fuel tanks, and the seamless, one-piece design includes convenient hold down grooves molded directly into the tank's shell to secure the tank, even in rough conditions. The non-permeable construction will not leach fumes into boat interior.

Tanks come complete with molded fill spouts, withdraw and vent fittings molded directly into the shell. Withdraw fitting has a 360 degree rotational capability for a convenient hook-up. Moeller uses the largest interior and exterior diameter fittings allowed in the industry to maximize the level of flow input during refueling.

Comments about Moeller Below Deck Permanent Fuel Tank:

Draw tubes in Moeller fuel tanks do not go all the way to bottom of the fuel tanks. Was told be Moeller that it is the industry standard to keep draw tubes 1" from the bottom of the tank so sediment is not pulled into engine. Consequently, this does not allow for full use of fuel tanks capacity. Easy fix - I purchased a MOE-033100-12 POP LOCK 12" Fuel Pick-up Assembly ($18), heated up the plastic draw tube, and then bent it into a gentle 90 degree elbow. Reformed draw tube slipped easily into fuel tank and now draws to within 1/16" of the bottom. One side note: the new draw tube does not have a strainer on it. So I installed an in-line fuel filter near the fuel tank as a preventative measure and to protect the engine fuel pump filter (easier to change in-line filter).

Comments about Moeller Below Deck Permanent Fuel Tank:

The Moeller line of fuel tanks are excellent replacements for old galvanized or fiberglass tanks. Everybody should know by now the problems that E-10 gas can cause. Replacing an old tank would be good preventative medicine.
