[AT] oil pressure

[CEE VILL]

Ralph,

It might be worth your time to try back flushing the small line to the gage. 
  Thinking about that system, it is a dead end circuit at the gage.  Any 
sludge that gets in the line stays there.  It is not like a circulating 
circuit where sludge may eventually wash on through.  I have seen a clogged 
line and gage cause a low reading.

My 2.5 cents.
