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.

Just a thought or two.
 
I would not run a plastic line that far to a pressure gauge. I'd bet we  
would all be surprised at
how much oil could be pumped out of the 1/8 inch line at 30 PSI or so.  
Really be fun if the leak were say.... Under the dash. YUCK!
 
I would run steel tubing just as we do for brake lines. We don't seem to  
have any problem 
running that the length of the car and they have considerably higher  
pressure on them.
 
I've used mechanical guages on many cars. just not on a Corvair.... yet.  
I've used the plastic
stuff that came with the guage a couple of times but never felt totally  
comfortable with it.
 
Of course your electric gauges respond immediately when you turn off the  
engine. You are
turning off the electricity to them....  DUH.
 
Just kidding.
