Sea-Dog Stainless Steel Flip Top Deck Fill – Gas – 1-1/2" Hose – 351110

The Sea-Dog Stainless Steel Flip Top Deck Fill – Gas (351110) is a durable and corrosion-resistant solution for safe and convenient fuel access on boats. Designed for gasoline fuel systems, this deck fill features a flip-top cap that stays attached during refueling, reducing the risk of loss while providing quick, one-handed operation.

Constructed from marine-grade stainless steel, the deck fill offers excellent resistance to rust and corrosion in harsh saltwater environments. The clearly marked “GAS” cap helps prevent fuel mix-ups, ensuring proper and safe fueling every time.

Compatible with 1-1/2 inch fuel fill hoses, this deck fill is ideal for use on a wide range of boats including center consoles, runabouts, and fishing vessels. The sleek, low-profile design provides a clean, professional appearance while maintaining a watertight seal to help protect your fuel system from water intrusion.

Key Performance Features

  • Keyless Operation: The cap features an easy-to-use "flip" tab. You simply lift the tab and twist slightly to open, making it one of the most convenient fills for high-traffic fuel docks.

  • Low-Profile Design: When closed, the cap sits nearly flush with the deck flange, reducing trip hazards and preventing dock lines from snagging.

  • Integrated Venting: This model is designed to work with your vessel’s existing venting system, featuring a standard 1-1/2" hose connection for the main fuel line.

  • Fuel Type Identification: The cap is clearly laser-etched with "GAS" in high-visibility lettering to prevent accidental cross-contamination at the fuel dock.

  • Bonding Screw: Includes a pre-installed grounding/bonding screw on the underside to connect to your boat's electrical bonding system, a critical safety requirement for preventing static sparks during refueling.

  • Hose Clamps: Use two (2) 316 stainless steel hose clamps on the 1-1/2" hose barb to meet USCG and ABYC safety standards for fuel systems.

  • Bedding: Use a high-quality marine sealant like 3M 4000UV or Life-Calk under the flange to prevent water from seeping into your deck core or fuel tank.
