Whitecap Fuel Vent - Rectangular Head, Straight, 9/16" Hose

The Whitecap Fuel Vent with Rectangular Head, Straight design and 9/16" hose is an essential marine fuel system component engineered for reliable ventilation on boats and recreational watercraft. This fuel vent allows air to enter the fuel tank during discharge, preventing a vacuum that would restrict fuel flow to the engine. Marine operators, boat builders, and maintenance technicians rely on quality fuel vents to ensure consistent engine performance and safe fuel system operation across freshwater and saltwater environments.

Manufactured from C.P. Zamac—a durable zinc-alloy casting material—the Whitecap fuel vent combines corrosion resistance with structural integrity, critical for prolonged exposure to marine conditions. The rectangular head design provides a stable, flush-mounting platform, while the straight configuration ensures direct hose connection without kinks or flow restrictions. The 3/4" hole size accommodates standard marine through-hull mounting, and the 9/16" hose connection accepts standard fuel line tubing, making integration straightforward during new builds or replacement installations.

This vent is ideal for owners maintaining older marine fuel systems or builders standardizing fuel tank ventilation on mid-size vessels where reliable airflow is non-negotiable. Installation requires a 3/4" hole through the fuel tank or deck area, with the hose routed to draw air from above the waterline to prevent water ingestion. Compatibility extends across most inboard and outboard fuel systems using 9/16" hose diameter, making this Whitecap model (MPN S-7031C) a proven replacement or upgrade choice for marine fuel system reliability.
