yes its just an o-ring........simple fix just make sure to coat the new o-ring in fuel so it wont roll on the way in.......also dont get an over the counter o-ring as it will most likely be Buena rubber and the ULSD will swell it up and degrade quickly...................Viton or EPDM is the best bet, if you have no source for these than get one from Chrysler
