Contact Hotel whiskey or Safe Air1
Robby,
I have installed the ER tanks on my -8, and Hotel Whiskey ships the most complete instructions I have ever seen, complete with color photos, etc. If I were you, I'd contact them immediately, do not rely on Internet heresay or other sources for info. Hotel Whiskey: 972-347-2781. Safe Air1: 817-939-2695, 817-821-4957.
