Fooshman on the forum was kind enough to share the info on this install. Maybe he will chime in and post the directions again. Yes it was an air hose from Home Depot.
I can't take credit for it. I found it somewhere on the internet (crappie forum?) myself when I was trying to researching trolling motors/depth finders for my boat.
I need to find a duller air hose for when I do mine.
