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

  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.

    Ordered this kit for my excursion, did exactly what it was intended for and invoice/install instructions were clear enough for me to install it myself

    All the o-rings you need

    This is all the o-rings you need for a fuel bowl rebuild, other than the FPR assembly. If you juuuust need o-rings go for this, but I'd recommend getting the replacement fuel pressure regulator housing as well.

    Chances are if you're doing a fuel bowl rebuild the FPR housing will be stripped or cracked...mine seemed fine until I went to reassemble (it's like the last step) and it was too stripped to hold torque.

    If you're leaking fuel from your fuel bowl it's time to replace those old dried up rings, if one is bad there are others soon to follow, relatively easy job once you get the bowl removed, do them all while you're in there and be good for another twenty years.

    Fuel bowl was leaking really bad and replaced all the o rings with this kit and now it's not leaking at all. Good price and really fast shipping, Thanks

    Easy job, just take your time and use the O-Ring Cheat Sheet. I think another page on how to remove your float bowl would be a great addition. And of course more stickers!
