Engine hoist and some straps is what i used for my 10hp 80gal. Like you said a bit sketchy but it works. For air line I used 3/4" rapid air with 4 drops. One thing that i would recommend is to make a loop system not a dead head one. Rapid air has some articles about how a looped (one that goes in a cycle) helps with flow and adds capacity to your air system. For me it was only another 50' or so to make everything connect so I figured why not.
