11 Viton o-rings and 4 Parker® fuel sleeves. 2 Fluorosilicone o-rings for the 7.3 yellow fuel drain valve core to fix your 7.3L Fuel Leak.

  1. 1 o-ring for the drain valve stem
  2. 2 o-rings for the drain valve to bowl seals
  3. 2 o-rings for the Water-in-Fuel sensor/Fuel Heater
  4. 1 o-ring for the Fuel Pressure Regulator housing
  5. 1 o-ring for the regulator piston bushing
  6. 2 o-rings for the fuel back check piston assembly
  7. 2 o-rings for bowl plugs
  8. 2 - 1/4" sleeves for the fuel lines feeding the cylinder heads
  9. 1 - 5/16" sleeve for the fuel return line
  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.

    Fuel. Bowl rebuild kit

    Posted by Jeff on May 24th 2019

    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.
