## Features

- Perfect Replacement: This fuel transfer tank vent cap replacement for Dee Zee Fill-Rite transfer tank cap and fit for standard 2" NPT threaded tank bung base. Designed to release dangerous vapor build-up and prevent over-expansion of the fuel tank. It allows air into the tank to prevent vacuum formation and collapse when fuel is drawn out.
- Heavy-Duty Construction: This diesel fuel transfer tank cap is made of reliabele materials that are waterproof and resistant to corrosion. The whole cap includes a removable transfer tank vented gas cap and 2-inch NPT base is heavy-duty cast iron, ensuring durability and long-term service for your diesel fuel transfer tank.
- Leak Prevention Design: The fuel transfer tank cap is equipped with a spring-loaded mechanism and an inside gasket. So while it will vent off pressure, it won't let in as much moisture as a cap with no gasket. When tightly closed, it forms a seal to prevent leaking and excess gas vapor venting, even during road travel.
- Ensure Fuel Safety: This diesel fuel tank cap is lockable and can accommodate a 1/4" - 5/16" diameter shackle padlock (not included). It provides added security by preventing theft, tampering, siphoning, and vandalism of the fuel tank.
- Easy to Use: The vented fuel cap is designed for easy installation and removal. To secure the cap, align it with the notch, push down, and twist it clockwise. To remove the transfer tank cap, twist it counter-clockwise to the notch to vent pressure, then push down and twist to lift and remove.
