Went ahead and ordered a new regulator (huma)as I am in there might as well improve it a little , I can feel the small leak coming out the hole where the air probe goes , Replaced gauge oring , to easy still leaking , Thought I would just order a o ring kit and valve for it , Nope there all over in the UK , Just wondering why no US based oring kits for the PP750?

The fill port O-ring #50 is a common source of leaking in SPA PCPs.

It is too soft so it eventually extrudes into the gap formed by the flat on screw #51. Replace it with a 90 durometer. The OEM size is a M1.5x5 but a -008 works equally well in this application.

Do you have a link to the document you cropped the image from?
I'm having difficulty finding an exploded view of the PP750 and the newer PP750L...
