The cap locks in place and spins freely once locked, so it cannot be forced or pried off; to open it, the owner turns the supplied key until the key hole lines up with the cap tabs. Two keys are included along with a cap attachment cable so the cap can't be misplaced dockside.\u003c\/p\u003e\u003cp\u003eThe deck fill body and cap are investment cast from 316 stainless steel, giving it strong resistance to salt-air corrosion and long-term durability in a marine environment. The cap measures 2-1\/8 inches in diameter with an 11-1\/2 NPSM straight thread pitch. The fitting is color-coded and marked with the international symbol for gasoline, making it easy to visually confirm the correct deck fill during fueling. Installation is with three #10 flat head fasteners (not included), and per USCG regulations a bonding wire must be connected to the fitting to prevent sparking during fueling.\u003c\/p\u003e\u003cp\u003eThis is the gas-specific version of Sea-Dog's Locking Hose Deck Fill line, built for 1-1\/2 inch hose. Matching diesel and water versions, and a 2 inch hose version, are sold separately under their own part numbers.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 351320L-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Size:\u003c\/strong\u003e 1-1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCap Diameter:\u003c\/strong\u003e 2-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 11-1\/2 NPSM straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension A:\u003c\/strong\u003e 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension B:\u003c\/strong\u003e 3-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type:\u003c\/strong\u003e #10 flat head (not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Investment Cast 316 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Type:\u003c\/strong\u003e Key lock, includes two keys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Two keys, cap attachment cable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.342 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Pack:\u003c\/strong\u003e 1 each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUniversal fit for boats with a 1-1\/2 inch gas fill hose and a standard deck fill mounting hole; not vehicle or engine specific.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size hose does this deck fill fit?\u003c\/strong\u003e The Sea-Dog 351320L-1 connects to 1-1\/2 inch hose, the standard size used on most gas fuel fill lines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this deck fill lock?\u003c\/strong\u003e Yes.
