The Perko Combination Vented Gas Fill/Tank for 1-1/2" Hose with 35° Angled Neck is a marine-grade fuel system component engineered for reliable, safe refueling operations on vessels and equipment where gravity feed or pressurized fuel delivery is critical. This vented fill cap assembly serves both recreational and commercial operators who demand corrosion-resistant, flame-arrestor-equipped fuel access points that meet USCG and EPA marine fuel system standards. Whether you're outfitting a center console, sportfisher, or auxiliary generator system, this combination fill/tank vent eliminates the need for separate vent and fill fittings while maintaining safety compliance.
Constructed from black polymer material with an integral flame arrestor, this fuel cap design prevents backflash during refueling while allowing internal tank pressure to equalize through the vent channel—eliminating vacuum lock and ensuring consistent fuel flow. The 35° angled neck geometry positions the fill opening at optimal angle for safe, splash-free fuel transfer without requiring awkward hose routing, while the flip-top cap provides quick-access closure and a positive seal. The no-ground-wire requirement simplifies installation on fiberglass hulls and composite fuel tank systems where traditional bonding may present complications, reducing both labor time and electrical vulnerability during fuel operations.
Marine technicians, boat builders, and fleet operators will recognize this Perko assembly as the industry standard for replacing corroded or damaged fuel caps on existing 1-1/2" fuel line systems. Retrofit compatibility is straightforward—the angled neck seats directly into standard marine fuel tank openings, and the hose barb accepts your existing 1-1/2" fuel line without additional adapters. Weighing just 0.45 lbs and compact enough for tight engine compartments, this vented fill cap is essential maintenance inventory for any serious marine fuel system upgrade or emergency repair scenario.
