I bought an Interdynamics A/C guage that you could check low and high sise with.I should have sprung for a nicemanifold set. Charged system and decided to look at high side. Plugged it in. Saw guage push halfway out. Only had enough time to close my eyes before the guage body hit the bridge of my nose, between my eyes!!!!!All refrigerant leaked out, alot of which was on me. I was still in the Oriellys parking lot, so I ran inside to flush my face. I then went outside, collected the pieces and tried to remain calm while I requested a new guage and replacement refrigerant.
I hope your pressure line failure was slightly less eventful.

I have been considering going to a 6.0 in the future, so thanks for the ideas and tips.
