Good To Know

Q: Will this cap fit both gas and diesel filler necks? A: It is listed for diesel applications on 2013-2018 Ram 1500, 2500, and 3500 trucks. Confirm your truck runs diesel before ordering.

Q: Does the magnetic feature replace the tether? A: The magnet helps hold the cap near the filler opening during refueling, but you should still seat it firmly when done. Check the seal periodically for wear.

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