7.3L Powerstroke External Oring Set

This kit is made by Alliant Power - the OE manufacturer for Powerstroke injectors. There may be a place to skimp on parts, but it is not here. It takes some effort to replace these o-rings and if they leak there are a number of symptoms you may experience such as hard starting, horrible oil consumption, engine miss, smoke, etc.

Take our advice and buy only the best external o-rings for your Powerstroke injectors!

Ford has spent years re-designing the number, layout, and composition of these orings to stem the tide of failures. Aftermarket orings often disintegrate in a year or less - 7.3L Powerstroke injector orings are not the place to save money!

Also be sure injector hold down bolts are torqued to 120in-lbs upon re-installation!

Each injector requires 6 parts as pictured. This 7.3 Powerstroke injector O-ring kit includes enough parts for 8 injectors - 48 pieces total. Order more than one if you are repairing multiple trucks.

We also have Powerstroke injectors, 7.3L Ford Powerstroke diesel glow plug kits, valve cover gaskets, internal harnesses, etc. All good things to consider while you are under those valve covers!
