The Perko Fuel System Locking Cap for 1-1/2" Non-Vented Fills is an essential security and safety device for any vessel relying on gravity-fed or pressure fuel systems. Fuel tank security is crucial to prevent unauthorized access, contamination, or siphoning, which can lead to dangerous situations at sea. This locking cap effectively seals your fuel fill opening, ensuring that dirt, water, and debris do not compromise your fuel system.

Recreational boaters, commercial fishing vessels, and liveaboards will find this accessory particularly beneficial in high-theft or high-contamination environments. Installation is straightforward, requiring only a basic hand-tight fit onto your existing non-vented fill neck—no tools or modifications are necessary. This cap is compatible with Perko fill models 0520, 0527, 0528, 0557, 0599, and 1270, making it a versatile addition to your marine equipment.
