  4. 1 o-ring for the Fuel Pressure Regulator housing

  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 Seal Success

    Posted by Derek on Feb 22nd 2021

    Extremely happy customer now that I don't wake up to a puddle of fuel underneath the truck. It's been a couple months and so far so dry. The procedures and diagrams provided were extremely helpful when replacing all these o rings. The removal and installation of the actual bowl assembly was much more difficult, but plenty of videos out there. After reviewing multiple sources regarding the product itself, I'm glad I went with OEM quality even if paying a slight premium. Customer experience was great and shipping was fast (received item within a week during the holiday season). Don't be afraid to reach out to Customer Support if you have any questions or concerns as feedback has been extremely helpful and timely.

    I ordered two other sets from different suppliers and the sleeves didn't fit. The sleeves that come in this set are a perfect fit!
