It replaces the original Perko cap on this style of fill, restoring a secure, corrosion-resistant closure over the fuel fill opening. The cap itself is chrome-plated bronze, mounted to a black plastic body, with a stainless steel beaded chain tethering the cap to the fill so it cannot be dropped or lost overboard during fueling. Built into the cap assembly is an integral tank vent equipped with a flame arrestor and an anti-surge valve, helping manage vapor venting from the tank while reducing the risk of flame entering through the vent path and limiting fuel surge out of the vent during rough water or fast fills. A deck plate key is included, sized to turn the cap for removal and installation. The complete assembly weighs 0.46 pounds and ships in a 10 x 5 x 1 inch package. Because the fill hardware is exposed to salt air, fuel, and repeated handling, the chrome-plated bronze and stainless steel chain are chosen for corrosion resistance over painted or plastic-only alternatives. This part is intended as a direct replacement for boat owners whose existing 1-1\/2 inch angled neck vented gas fill cap has become worn, cracked, seized, or lost, restoring the fill to factory-original fit and function without changing the deck plate or the mounting hardware underneath.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
