Riffraff Diesel Fuel Cap 1994-2007 7.3L, 6.0L

Replace your aged out plastic fuel tank fill cap with a new Billet Fuel Cap made from 6061 Aluminum that features a brand new inner ratcheting cap. 

Fitment Note: Make sure that your cap has the threads like shown above, and not a snap cap that was on a few of the models like Early 1999 F-Series, or Excursion built in 1999. 

*Note: Anodized Color on Aluminum can be discolored / damaged by chemical engine cleaners. Use only soap and water to clean.
