New Engine... NO Oil Pressure!!!!

[vwtype53@yahoo.com (Benjamin Harder)]

Eric,

  Yes, I am using a 5 bar gauge and sender.  In fact, this exact
gauge and sender was used sucessfully on my 1.8 16v engine that
was in my '80 just months ago.  But I tried other gauges and senders
as well to make sure... mechanical gauge is next on the list.
