    I had read somewhere that all 7.3L plugs were the same but there not but they look like they are good quality so I’ll use them for something else.

    hpop reservoir fill plug

    Posted by KJ on May 28th 2020

    fits on top of the hpop reservoir. Stripped out when removing for the oil change. This was a great match for the stripped plug removed. Don't think about it and order one for your 7.3 to have on hand.
