I have a 97 7.3 and have a few questions on the hpop.does the hpop get its oil from the motor or is it just filled by the plug on top of it.and if it does not get oil from the motor how do you go about changing it and how often should it be changed. thanks for any help

HPOP ? High pressure oil pump ?

Changed every time you change your oil?

Yeah that's what HPOP means.

And yeah, change your oil, and new oil pushes through your entire system. Including the HPOS. High Pressure Oil System.

Damn! Sounds like it'll add up quick for an oil change with the HPOS.

When you change the engine oil. The low pressure oil pump at the bottom of the motor, in the oil pan, will feed the high pressure oil pump. The HPOP will then push that new oil through the whole HPOS. So no need to change or drain anything other than what's in the oil pan.

Like said above, there is no need to change the oil in your HPOP, just do a regular oil change and it will cycle through, these trucks take a lot of oil anyways, oil changes arent the cheapest but its not bad
