and or I have bad eyes. Yours was set up for????? Paintball? Has a 200 or 300 DIN fitting? Attached is a pic of our standard tank and "yoke" for filling a Disco/Mrod . If you had a standard tank you could jump on ebay or hit a paintball shop for a yoke -$25- then you need a hose from the yoke to a femaile foster fitting then you are all set.
