<VV> Plastic tube for oil pressure gauge

[NicolCS at aol.com]

I had one, and only one, mechanical oil gauge in a Corvair.  It took about 30 
seconds to respond to a change in oil pressure, such as shutting the engine 
off.  I also felt that it read a couple of psi low.  (stretch in long line?).  
Low readings at hot idle were always scary (about 5 psi).  It was kinda fun to 
shut off the engine and see how long it took to respond though.  Now I have 
electric gauges that respond instantly.
