The cap combines a zinc-alloy exterior with a rubber sealing ring, a chained valve cover to avoid loss, and an included aluminum key so you can swap the cap without hunting for tools. It’s designed for long-term resistance to rust and oxidation, and Kylazer backs it with a five-year warranty against manufacturing defects.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know this cap fits my boat?\u003c\/h3\u003e\n\u003cp\u003eCheck your fuel filler diameter and thread standard: this cap is made for a 2-inch opening that meets the 1-1\/2 NPT specification. Some newer boats built after 2012 may use EPA-compliant systems with different configurations that are not compatible. If you’re unsure, measure your filler or consult your boat’s specifications before ordering.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for 2-inch fuel filler ports with 1-1\/2 NPT threads.\u003c\/li\u003e\n  \u003cli\u003eMay be incompatible with some post-2012 EPA-configured tanks.\u003c\/li\u003e\n  \u003cli\u003eMeasure the filler or refer to manufacturer documentation for certainty.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and components are included, and why do they matter?\u003c\/h3\u003e\n\u003cp\u003eThe cap’s body is zinc alloy for corrosion resistance, paired with a plastic rubber O-ring that forms the sealing surface against the tank. The kit includes a chained valve cap to prevent loss and an aluminum alloy key for easy removal and reinstallation—no extra parts required.

A well-sealed cap can lower contamination risk during storage and routine operation, helping keep the tank environment cleaner. Always follow manufacturer guidance for fuel handling and storage.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTight rubber seal cuts down on dust and moisture entry.\u003c\/li\u003e\n  \u003cli\u003eDurable metal body helps resist corrosion at the filler opening.\u003c\/li\u003e\n  \u003cli\u003eChained cap prevents accidental loss while refueling or during transit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The Kylazer replacement gas cap is aimed at boat owners, mariners, and fleet managers who need a reliable, ready-to-install cap for a 2-inch (1-1\/2 NPT) fuel filler. It’s especially useful if you want a low-maintenance, corrosion-resistant option with a tethered valve cap and included key—ideal for older and mid-era vessels using standard filler threads. If your boat has an EPA-specific or newer fuel system configuration, verify compatibility before purchase.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this cap fit my 2-inch boat fuel filler?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes if your filler is 2 inches with a 1-1\/2 NPT thread; verify measurements and post-2012 EPA systems may differ.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What maintenance does the cap need?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Inspect periodically and replace the O-ring about every five years; clean threads to prevent corrosion.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Kylazer","offers":[{"title":"Default Title","offer_id":48082981912734,"sku":"B0FJWDZ43T","price":58.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/kylazer-front-view-fuel-cap.jpg?v=1785821639","url":"https:\/\/northtrailauto.ca\/products\/kylazer-boat-fuel-filler-cap-2-inch-1-1-2-npt-with-chained-valve-cover-and-aluminum-key-zinc-alloy-rubber-seal","provider":"North Trail Auto","version":"1.0","type":"link"}
