[Bricklin] Air Leak Update

[Maycinc at cs.com]

I'm still trying to track down the door air leak on ol' 1343.  I put a 
check valve in the line to the compressor so that's not it.  None of the 
fittings are leaking. The doors stay up even after the pressure bleeds down so it's 
not the solenoids.

Thought it might be the pressure gauge but I put soap all over it and 
couldn't detect any leaks.   So that leaves a leak in the regulator, water trap, 
or the line to the tank.  

Any idea how to see if it's the regulator?  It's a rather slow leak as it 
takes at least 6 to 8 hours for the pressure to drop to zero.  

I guess 7 years with no leaks is a pretty good run.
