  Fuel Filler Cap – Mopar OEM #52030377AB
  Seal It Right. Drive with Confidence. Mopar Original Equipment.

  Eliminate fuel vapor leaks, check engine lights, and poor fuel economy with the Mopar Fuel Filler Cap (52030377AB)—a genuine OEM replacement cap engineered to meet the exact pressure, sealing, and emission specs for your Chrysler, Dodge, Jeep, or Ram vehicle.

  Unlike aftermarket caps that may trigger EVAP system faults or fit loosely, this cap is designed to lock securely with the proper torque click, creating a tight seal that keeps fuel vapors in and contaminants out. It’s emissions-system approved, built to resist fuel degradation, and compatible with onboard diagnostic systems—helping clear codes like P0456 or P0440 related to EVAP leaks.

  Why This Mopar Fuel Cap Stands Out:

  • ✅ Genuine Mopar OEM Part #52030377AB – Exact factory replacement

  • ⛽ Maintains proper seal on fuel filler neck—prevents vapor loss and CEL codes
