Good To Know

Q: Does this gas cap include the vent hose? A: Some versions may include a brief vent line, but it is recommended to transfer your existing breather tube or install a fresh vent valve to ensure proper tank ventilation.

Q: How do I know if my current cap needs replacing? A: If you smell raw fuel while riding, see gas seeping around the threads, or notice the rubber gasket inside is cracked or dry-rotted, it is time for a replacement cap.
