John,
You should have some sort of Truck Stop shop around your area.  Take you old piece there, and know what length you want, and ask them what they have like that for air brakes.
The Bricklin uses that to lift the the doors (about 100# ea).  You onboard compressors use a pressure switch that comes on about 110 and off at 150psi.
Never had a problem with that.  Depending on the dia you are using you'll want to get the right fittings, again ask the counter person at the truck stop.  There are 2 types that I know of, one with the penis in the fitting and one where you have to purchase the metal insert for the dia. hose you are using.  If you don't have either of these metal inserts for the hose, the hose will collapse when you tighten the  nut on the ferrel.   I'll send you pictures of the 2 connectors in another email.
