If the ground is bad, the gauge should be pegged, correct?

at the very least, put a mechanical gauge on it to try to verify if

Many thanks for all the help. I've now sniffed my oil, and it smells
like oil, so I'm pretty sure my IP seals are OK. I've also taken a
good hard look at the OP gauge needle when I switch off the car, and
it drops slowly, not instantaneously like the Temp gauge, so I THINK
the issue is

Likely your injection pump seals have failed, you are filling the
crankcase with diesel fuel.
Change the oil and replace the IP.

Check for flow (a bad sender usually indicates erratic pressure then
quits altogether, it won't slowly fade away), but if you think the
oil is thin, smell it.
If it smells of diesel fuel, your IP is leaking into the crankcase
and you will damage the engine soon.

On some of the old cars we would hold the engine revs up and loosen the
sender (actually the pressure tube on the old cars) until oil started coming
out around the threads and was obviously under high pressure. This was done
when the gauge was reading very low. WARNING! If you back it out
