Attwood Gasoline Deck Fill - 1-1/2" Stainless Steel Alloy

The Attwood Gasoline Deck Fill – 1-1/2" Stainless Steel Alloy is a marine fuel system component engineered to provide safe, reliable fuel access on recreational boats and fishing vessels. Anyone who operates a gasoline-powered boat knows that a secure deck fill is non-negotiable—it prevents fuel spillage, keeps water and debris out of your tank, and clearly marks the fuel port so you never confuse it with water or waste intakes. This 1-1/2 inch stainless steel alloy fill serves that critical function while standing up to the corrosive saltwater and freshwater environments that test marine hardware daily.

Built from corrosion-resistant stainless steel alloy, the Attwood deck fill is rated and color-coded specifically for gasoline to prevent dangerous misfueling. The flush-mount design sits flush with your deck for clean aesthetics and safer footing, while the slotted cap accepts a separate key lock to prevent tampering or accidental fuel loss underway. The O-ring seal on the cap creates a watertight closure, keeping spray, rain, and wave wash from contaminating your fuel supply—a particularly important feature when running through chop or in rough conditions. The 1-1/2 inch inner diameter hose connection is the standard size for most mid-range recreational and fishing boats.

Anglers and boaters upgrading aging deck fills, replacing corroded hardware, or building out new fuel systems will find this Attwood fill compatible with standard 1-1/2 inch fuel hose and marine fuel system plumbing. Installation is straightforward—it mounts through the deck with a simple fastening system and connects to your hose via a barbed fitting. Whether you're refueling at a remote fishing lodge, a busy marina, or anchored offshore, a reliable gasoline deck fill means you spend more time on the water and less time worrying about fuel system integrity.
