oil pressure gage stuck on 80
okay...the gauge is on 80, but the actual pressure varies? you could just say "screw this" and get yourself an entirely mechanical one~http://www.delcity.net/store/Gauge- Line/p_804103.h_804104.t_1.r_IF1003? mkwid=T66CljFo&crid=8229606509&gclid=CMjd9L3h4LoCFaUWMgod MGQA2w
Unplug the sending unit that screws into the engine. Start the truck. If gauge drops to zero sending unit is most likely stuck. Replace it. If not, gauge unit in the instrument cluster is most likely bad. The gauge is not serviceable by itself. To fix this the whole instrument cluster must be replaced. HTH. -Jim
