Well with the stock fuel bowl gone I was able to notice that my hpop is leaking from the "non serviceable " plug.
I did some searching and found that IH has a kit for a dt466 hpop that will work on our 7.3's.origonal thread - This is how to repair the "non-serviceable" plug on the HPOP
IH part number for the dt466 HPOP kit - 1842906C92.
IH part number for the Hpop mounting gasket 1825163c2 $21.29
IH part number for the Hpop resivore gasket 1823670c1 $9.61
Local IH dealer wanted 75 for the hpop kit. i found it online for 45$ so i ordered it. The kit gives directions on how to perform the procedure. The only problem is the kit only comes with one large o ring to seal 1 of the 2 hpop fittings coming out of the pump. So you will need to purchase another oring for the other hpop fitting.
the pump must be removed because of a check ball in the pump.
The pics below show the way to position it, with the ipr up to make sure the check ball does not fall out. The check ball will only fall out if you remove the "non serviceable" plug. So if you remove the plug, be sure to have the ipr pointed up!
^^^^Here it is with the fittings removed. You can see the non serviceable plug on the right in the bottom of the coke bottle
^^^Here is looking down the ipr hole. The n.s. plug has a boss/bar extending off of it which is what holds that check ball in place. You can see the edges of the ball if you look behind or around the boss

If the check ball is not in it's little hole, the truck won't start. So be sure not to blow the pump with compressed air or anything, which may blow the check ball out of the pump.
To remove and install the stock hpop, I used the adrenaline hpop instructions.
