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
