Vented Gas Cap Fuel Transfer Tank Vented Cap Replaces With Threaded Neck Car

Vented Gas Cap for Fuel Transfer Tank

This vented gas cap replaces a worn or lost cap on a threaded-neck fuel transfer tank, letting air enter as fuel is drawn out to keep flow steady.

Overview

This vented gas cap is built for fuel transfer tanks that use a threaded neck and need reliable venting during transfer. The cap threads on securely and allows air to pass through so the tank does not pull a vacuum while fuel is being pumped or poured. It is a practical replacement part for anyone running a transfer tank for equipment, vehicles, or job site fueling.

Good To Know

Q: Why does a transfer tank need a vented cap? A: Venting lets air enter the tank as fuel leaves, which prevents a vacuum that can slow or stop the flow. A sealed cap on a non-vented tank can cause poor transfer and pressure issues.

Q: How do I know this cap will thread onto my tank? A: Check that your tank has a threaded filler neck and compare the thread size with the cap specs before ordering. Fit can vary between tank brands and production runs.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
