Moeller 621501101 Tempo Manual Vent Gas Cap

The Moeller 621501101 Tempo Manual Vent Gas Cap is a replacement fuel-system component designed for compatible marine applications. Its manual vent design helps support proper tank venting during fuel-system operation, while the cap provides a secure closure for the appropriate fill or vent assembly. Use this part when replacing a worn, damaged, or missing cap on a compatible Moeller Tempo system.
The manual vent configuration offers a straightforward solution for applications that require user-operated tank venting. A properly fitted gas cap can help maintain the intended function of the fuel system and protect the associated opening from exposure when the system is not being serviced or refueled. Confirm compatibility with your existing Moeller equipment before installation, as fuel-system components should match the tank, filler, and vent configuration.
Manufactured under the Moeller brand, part number 621501101 provides a direct reference for identifying the correct replacement component. The cap is suited for maintenance, restoration, and repair work where the original manual vent gas cap needs to be replaced. For best results, inspect the mating area and related hardware before installation, and follow the equipment manufacturer’s service instructions and applicable marine safety requirements. This component is identified as the Tempo Manual Vent Gas Cap and should be selected based on application compatibility rather than appearance alone.
