Its locking cap is designed to prevent fuel theft: the cap spins freely while in the locked position, and to unlock it the owner turns the included key until the keyhole lines up with the cap tabs. Two keys are supplied along with a cap attachment cable, so the cap stays tethered to the boat and cannot be misplaced during fueling.\u003c\/p\u003e\u003cp\u003eThe fitting is investment cast from 316 stainless steel, a corrosion-resistant alloy suited to long-term saltwater exposure, giving the deck fill durability well beyond stamped or plated fittings. The cap measures 2-1\/8 inches in diameter and threads onto a 11-1\/2 NPSM straight thread pitch. The body is marked \"Diesel\" and color-coded per the international deck fill identification system, so crew and fuel dock staff can confirm the correct fuel type at a glance and avoid a costly misfueling.\u003c\/p\u003e\u003cp\u003eInstallation is straightforward: the deck fill mounts with three #10 flathead fasteners (fasteners not included), and it accepts standard 1-1\/2 inch fill hose. Because a deck fill sits in an open fuel-vapor path, USCG regulations require a bonding wire be connected to the fitting to prevent sparking; installers should wire the bonding connection as part of the install. This deck fill is sold individually.\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 351321-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Marking:\u003c\/strong\u003e Diesel\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 inch\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\u003eCap Type:\u003c\/strong\u003e Locking, spins freely when locked\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Keys:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCap Attachment Cable:\u003c\/strong\u003e Included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type:\u003c\/strong\u003e #10 FH (flathead), 3 required, 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\u003eWeight:\u003c\/strong\u003e 0.966 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Pack:\u003c\/strong\u003e 1 each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBonding:\u003c\/strong\u003e USCG-required bonding wire connection to prevent sparking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat fuel type is the Sea-Dog 351321-1 deck fill designed for?\u003c\/strong\u003e The 351321-1 is marked and color-coded for Diesel fuel, so it should be installed on the diesel fill line rather than a gasoline or water fill.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size hose does this deck fill accept?\u003c\/strong\u003e It is built for 1-1\/2 inch fill hose; a separate 2 inch hose version of this locking diesel deck fill is available as a different part number if a larger hose is needed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the locking cap work?\u003c\/strong\u003e The cap on part 351321-1 spins freely while locked so it cannot be forced open; to unlock it, turn the supplied key until the keyhole lines up with the cap tabs, then the cap can be removed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many keys come with the deck fill?\u003c\/strong\u003e Two keys are included with the Sea-Dog 351321-1 locking deck fill, along with a cap attachment cable to keep the cap tethered to the boat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 351321-1 deck fill made from?\u003c\/strong\u003e It is investment cast from 316 stainless steel, a corrosion-resistant grade chosen for long-term durability in a marine saltwater environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size are the mounting fasteners?\u003c\/strong\u003e The deck fill installs with three #10 flathead fasteners; the fasteners themselves are not included with part 351321-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the cap diameter and thread pitch on this deck fill?\u003c\/strong\u003e The cap measures 2-1\/8 inches in diameter and uses an 11-1\/2 NPSM straight thread pitch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a bonding wire required for installation?\u003c\/strong\u003e Yes, USCG regulations require a bonding wire be connected to the 351321-1 deck fill to prevent sparking around fuel vapors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this deck fill weigh?\u003c\/strong\u003e The Sea-Dog 351321-1 diesel hose deck fill weighs 0.966 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the deck fill come with a non-locking cap option?\u003c\/strong\u003e The 351321-1 is the locking-cap version; Sea-Dog also offers a replacement non-locking cap (part 351391-1) as a separate accessory for this deck fill line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this deck fill sold as a single unit?\u003c\/strong\u003e Yes, the 351321-1 is packaged and sold as a standard pack of 1 each.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988759228635,"sku":"S-D-351321-1","price":48.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/7144.jpg?v=1784428934","url":"https:\/\/www.goodvibesmarina.com\/products\/sea-dog-351321-1-diesel-deck-fill-1-1-2-hose-316-stainless-steel-with-locking-keyed-cap-and-chain","provider":"Good Vibes Marina","version":"1.0","type":"link"}
