Alliant injector o ring kit
 

got 8 of these off ebay for pretty cheap just to have on hand when I need them but one of the bags is missing the little snap ring. Where does the snap ring go and does it really need to be replaced since it isnt included with the motorcraft kit from Ford. Thanks for the help

you can reuse the Snapring

The Snapring is for the Oring in the VERYTOP the inject where the HPO Rail goes the snapring hold that top oring in

Aliant oring kits are the Only ones that have that top oring for the HPO RAIL

I don't think you can get the snap ring out without breaking it. You can replace that top seal without removing the snap ring, just working the new one into place, but it's not fun.

Make sure the ferrel stays above the o-ring.You can go to the alliant web site and get a picture of the oring and ferrel at the 6.0 tech bullitens section. I tried putting a link but it was't working, im new at this.
