Yeah without the valve the gauge will just dance all day. I might just get that tester linked to on the first page. It wouldn't be too hard to adapt a valve for the harber garbage but if you can take it back the other isn't much more in price online.
I think harbor might have added a valve to the gauge too but I haven't been there to check

Well, i did it and that is the only valve in the line so it didn't work. with limited access to fittings, i managed to adapt one of the other adapters in-line, #6 in the kit (according to the manual: http://manuals.harborfreight.com/man...3999/93644.pdf) with another $10 worth of brass fittings from the hardware store.
an easier way would be if you could find another one of the mini quick couplers (dunno if HF carries these, i couldn't get back to the store and they don't list them online), then you could use just a single 1/8" pipe coupler by snapping the extra QC onto the #17, putting the 1/8" pipe couipler on that, screwing the #10 adapter (w/valve) into that and then you could snap the guage hose onto that.
if you have a turbo though, you won't be able to stuff all that under it at #7 cylinder. i prolly have to go back and replace one of the straight fittings with an elbow.
my compression checked out ok but guess which cylinder had the GP with the burnt off end? grrrr.....
good luck with yours. if you come up with any better or shorter solutions, lemme know. i still worry about that #7 cylinder.
