First I had to remove the stock schrader valve at the top of the shock where the nitrogen normally goes.
Then I opened up the hole with a 21/64 drill bit and retapped the hole to 1/8 npt (pipe).
Then I installed a brass 90° street elbow (extra long 1.19") which are pretty hard to find locally, but I found them online at Vulcan Lighting.
The female 1/8 opening then accepts the non swivel end of the hose that was supplied with the reservoir.
Keep in mind I am plumbing this so I can use the supplied line.
Of course there are different reservoirs and ways to plumb the system available.
