Sea-Dog 351320-1 Cast 316 Stainless Steel 1-1/2 Inch Gas Deck Fill with Key

The Sea-Dog 351320-1 is a 1-1/2 inch hose gas deck fill built from investment cast 316 stainless steel for corrosion resistance in a marine environment. It is designed for filling a boat's gas tank through the deck, with a slotted cap that requires the included key to open and close, adding a layer of security against unauthorized access or tampering at the fill point. The cap diameter measures 1-7/8 inches, and the fill uses an 11-1/2 NPSM straight thread pitch. A chain attaches the cap to the fill base so the cap cannot be misplaced once removed for fueling.

This deck fill installs with three #10 flat head fasteners (not included), so the installer will need to source the appropriate hardware separately. Because it is a fitting for a boat's fuel system, USCG regulations require a bonding wire to be connected to prevent sparking; the deck fill itself does not include the bonding wire. The overall item measures 3.5 x 5.25 x 7.88 inches. This is the gas-specific version of Sea-Dog's keyed hose deck fill line; a separate 2 inch version with a 2-1/8 inch cap diameter is also made, so boat owners should confirm the 1-1/2 inch hose size matches their existing fuel fill hose before ordering.
