Perko 0542 Vented Fill f/1-1/2" Hose - Angled Neck - Gas - Black

The Perko 0542 Vented Fill for 1-1/2" Hose with Angled Neck in black is a critical fuel system component designed for gasoline tanks on recreational and commercial vessels. After years on the water, any experienced boater knows that proper fuel management—including reliable tank venting and filling—is non-negotiable for safe, trouble-free operation. This marine-grade filler cap assembly prevents fuel vapors from accumulating in the tank while providing a secure, angled entry point for refueling at the dock or underway.

The angled neck design allows for ergonomic fuel hose routing and reduces the risk of spills during refueling—a practical advantage when operating in choppy conditions or tight marina spaces. The vented construction ensures atmospheric pressure inside the tank, preventing a vacuum that would otherwise slow fuel delivery to your engine. Built with marine-grade materials and finished in corrosion-resistant black, the Perko 0542 resists the salt spray, UV exposure, and thermal cycling that rapidly degrades standard automotive filler caps. The compact footprint (6 x 4 x 10 inches) integrates seamlessly with 1-1/2" fuel hose, a standard diameter on mid-sized recreational and commercial fishing vessels.

Boaters upgrading aging fuel systems or replacing a damaged filler cap will appreciate Perko's reputation for durability and reliability—the brand has been trusted in marine applications for decades. Installation is straightforward: the angled design accommodates the most common deck and cabin-top fuel tank configurations without requiring custom routing. Whether you operate a center console, cruiser, or fishing platform, the Perko 0542 ensures consistent airflow into your tank while keeping contaminants and water out, extending tank and engine life while you focus on the water ahead.
