CM4717 Injector Seal Kit

Worked on 2006 Ford F-150 with 4.6L V8

The injector on the left is as removed from 2019 6.8ltr V-10 E350 Superduty Cutaway Chassis (under a motorhome). You can see that the upper and lower o-rings are different. The lower has a larger I.D. and is a bit thinner. It also fits a bit loose on the injector. As best I can tell this part supersedes the smaller o-ring. You can see these o-rings installed on an injector on the right of the pic. The overall diameter is approximately .024" larger. It was a bit trying to get the lower o-ring on, but not too hard. They installed fine, nice snug fit into the intake runners. The pictures of this part caused me some concern, thinking I was just getting the uppers. Don't fret, they work great on the lower as well.

I always use new oring seals when removing fuel rail. I don't want to take a chance of leaking fuel. There were enough to replace all upper seals. Some other packages only have 2 seals. The price was cheaper buying all of them in one package.

worked very well thank you

Perfect fit for my 2016 f150 5.0 quick and easy to install. There are 10 in a bag. Not enough to both sides of all injectors.
