HPOP fill plug
First off, How come Ford made the fill plug for my hpop something i need a square bit to get loose? I thought I read on here that they are allen wrench style. Well my plug on top is a square drive. Secondly, how come it couldn't be 1/4 inch? Instead its just smaller like a 7/32 or 3/16.

Alright i will look into that as soon as i can figure out how to get this one loose. I figured it wasn't the right plug because i went to napa and O'Reillys lookin for something square and just under 1/4 inch but neither of them had something. And i know that they should be allen wrench style plugs.

That seems odd to me... When I filled my 94's HPOP, I just used a 1/4" ratchet with an extension on it. It worked like a charm.....
If you have an old extension, you could grind a small amount off of each side...

Ya it seemed odd to me when i first actually tried to open in with an allen wrench in hand and the plug was square.
So was yours square too? and thats exactly what i was thinking about doing. Just grabbin a cheap 3/8 to 1/4 drive and shaving off a little on each side until it fits.

Weird. I tried putting a 1/4 extension in there but it didnt fit. Thats why ive been looking for a 3/16. Im curious if yours is a 94 and and mines a 95 and the other guys are 96+. Did the earlier year psd's have this square plug and the later ones had the allen wrench style?

Ok makes sense i guess. Well i will try to shave down a 1/4 inch extension tomorrow. I think my HPOP is low cuz im having hard starts. Oh when you refill it do you just use normal engine oil?
