Gen3 Marine 3 Inch Stainless Steel Fuel Deck Fill with Locking Key Cap

This Gen3 Marine fuel deck fill is a 3 inch stainless steel deck fitting designed to give boaters a secure, corrosion-resistant fill point for the fuel tank. It is machined from 316 stainless steel, a marine-grade alloy chosen for its resistance to saltwater corrosion and long service life in exposed deck installations. The cap is slotted for easy opening and closing with a standard deck-fill key, and it requires that key to open, adding a layer of security against unauthorized access to the fuel tank. The cap stays attached to the base via a chain, so it cannot be dropped overboard or misplaced while the tank is being filled.

The deck fill connects to a 1-1/2 inch hose and uses a straight thread design. It is a universal-fit fitting suited to a range of boat deck installations. A key is included with the unit; deck installation hardware is sold separately.
