CST Fuel Caps

Regular Fuel Caps
CST regular fuel caps make an excellent replacement for lost or faulty fuel caps, which occur over time. CST's newer fuel caps are constructed from high impact plastics that are environmentally friendly.

Locking Fuel Caps
CST locking fuel caps are nearly impossible to be removed without the appropriate key. CST locking fuel caps can also be used as a regular fuel cap, locking the cap only when needed.


  • CST fuel caps are manufactured and designed to meet or exceed original equipment specifications.


  • CST fuel caps are independently tested and have passed all United States government standards for crash impact integrity.


  • CST fuel caps will satisfy the IM240 emission standard that is required in some states.
