The Attwood 66419-3 is engineered for marine environments: its composite construction resists corrosion, it meets ABYC standards, and its 90° P-trap design removes the need for an anti-siphon loop in the vent hose in many installations.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this vent stop water from entering my fuel tank?\u003c\/h3\u003e\n\u003cp\u003eThe 90° P-trap geometry forms a splash-resistant barrier that redirects waves and washdown away from the vent opening while still allowing air to pass.

The Attwood 66419-3 composite 90° P-trap fuel tank vent is intended for boat owners, naval technicians, and marine maintenance professionals who need a compact, ABYC-compliant vent that reduces water intrusion and simplifies vent hose routing. It's especially useful for recreational boats where corrosion resistance, ease of replacement, and tidy hose runs matter. If your vessel uses 5\/8\" I.D. vent hose and you want a reliable, splash-resistant vent that eliminates the need for an anti-siphon loop in many setups, this Attwood vent is designed to fit that need.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What hose size does the Attwood 66419-3 fit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It is made for 5\/8\" inner-diameter vent hose; secure it with a standard hose clamp.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I still need an anti-siphon loop with this vent?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Its P-trap design eliminates the need for an anti-siphon loop in many installations, but follow local codes and installation instructions.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"attwood","offers":[{"title":"Default Title","offer_id":48084368064670,"sku":"B001YXO148","price":29.91,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/attwood-66419-3-front-profile.jpg?v=1785851898","url":"https:\/\/northtrailauto.ca\/products\/attwood-90-p-trap-fuel-tank-vent-composite-5-8-i-d-splash-resistant-black","provider":"North Trail Auto","version":"1.0","type":"link"}
