[s-cars] Oil Pressure Gauge & Sender Install?

[Chris Hemberger]

Howdy Folks,
   
  Relatively new to the S-Car list and have been lurking for a bit but some may remember me from the 200q-20v list. Yes, I have made the upgrade to an S6 like many of you, though I still have my 200q..
   
  I have a query regarding installation of an aftermarket oil pressure gauge - which the bean-counters erred in omitting.  Does anybody know for certain what aftermarket gauges are compatible with the OEM sending unit as used on the 3B - and I believe early versions of the AAN/S4?
   
  Also, it appears the port where the 3B sender is normally installed is now 'plugged' - is this simply a threaded plug or is it something more permanent? I would prefer to utilize this port rather than a T-fitting in the pressure warning sensor port now in use.
   
  Any help/BTDT on the topic would be appreciated - I have searched the archives, among other sources, with no real luck or direction..
   
  Thanks in advance,
