[herb fraser]

So not sure what to look for , my Autometer oil pressure gauge shows no pressure , but I know there is pressure I one a port and loads of oil squirted out

there is power at the gauge , on power ate the sending unit that I can see any thought would be very helpful
Thanks in advance , Herb

FIXED, turns out the line from the gauge to the sending unit had a brake in it somewhere , I replaced the line and it works fine , thinkin maybe somewhere in the connectors for the harness ?
