Alrighty boys, I think I figured it out, with a little help from you...
I found a 1/8" plug at Home Depot. Gonna plug where the 1/8" hose compression is, and replace the 1/4" pressure relief with a quick release setup. I figure as long as I make sure I release the pressure in the tank when I'm done, I should be good to go.
I think I made a bigger deal out of it that it was. It's my first mod in a while...I'm a little rusty.
Thanks again guys...
I'll update when I get 'er all dialed.
