High Pressure Oil Rail End Plug & Gasket Set (4) - Ford 7.3L (94-03)
Oil rail plugs located on either end of the cylinder head require a specialty o-ring if they begin to leak. This is the large round 1 3/4" plug with the 1/2" drive socket hole. During engine rebuild it is good practice to replace these plugs and gaskets since they are almost impossible to reach once the engine is installed in the bay.
Order of 1 is 4 plugs, gasket o-ring and instruction sheet.
Ford and Navistar's instructions require the use of LocTite 277 threadlocker on the Oil Rail End plugs

It works as advertised and the "O" ring design is a big improvement over the OEM 2 ring design.

Well-made
Well made product that definitely seems better than stock. Getting the old one out may be a pain, but once you do, this one fits great.

Rail End Plug Installation Tip
The right plug is especially a bear to get at. Go to your local hardware store and buy a piece of 1/2" key stock about 1.5" long. You'll find it in one of those "specialty" hardware trays in the big box stores.
Insert the key stock into a 15mm swivel gear wrench, then work the key stock into the recessed !/2" square hole in the old plugs. It takes both hands but it brought it right out with a little of grunt effort. Worked for me.
