Had similar problem with mine.  Futzed with if for a few months--moving needle, etc.--then finally sent it to Morris at 
West Valley Instruments; couldn't be happier with the results (also found almost 20psi of oil pressure at idle I had 
never had before).

Not cheap--about $170 all told--but well worth it.  Also, the fluid/gas line from the sender will be different if you 
still have the original gauge.  My original had a metal cloth-like protective sleeve--wouldn't protect much--and the 
refurb will have a wound wire 'sleeve' that is somewhat less flexible and slightly larger diameter.
