  1. 1 o-ring for the drain valve stem

  10. 1 - 3/8" sleeve for the fuel feed line.

Order of 1 is a set of 11 o-rings and 4 sleeves.

NOTE: This kit does not contain the REGULATOR POPPET SEAT. This is a separate kit only available as a FORD kit. The Regulator Rebuild kit can be purchased separately as F81Z9B249BB on our website.
NOTE: If you remove the fuel rail lines from the cylinder heads, this kit contains the fuel sleeves for the filter bowl ends only. It is recommended to also replace the sleeves on the cylinder head end of the fuel rail lines once they have been removed as they will no longer seal properly.  Order part GZ-7-004 to supplement this kit.

    Purchased complete fuel bowl rebuild kit along with upgraded O-rings for the fuel water separator from Riff Raff. Followed the instructions given with the kit along with a YouTube video of the exact same kit. Very easy DYI install. No more diesel fuel smell or leaks. Great stuff.

    7.3 Fuel Bowl Rebuild

    Posted by Unknown on Sep 18th 2018

    Thanks for the great parts and the other reviews here that helped my pull the trigger on this kit to rebuild my leaking fuel bowl. The parts are quality and the included reference chart made it easy to make sure the correct rings got into the right places. Whole project took just over 2 hours and worked like a charm to stop diesel from accumulating in my valley.
