Not all, but some...

There are two ranges of aftermarket VDO senders for the oil pressure. Sounds like you have the 150 PSI sender, and you need the 80 PSI one.

A friend once told me, "All analog meters are actually ammeters." He seems to be right so far. They (almost?) all work by running a current through an electromagnet and using that to pull the (spring-loaded) needle. More current, more magnetic force to overcome the spring force.

The context of the remark was that a voltmeter is really just an ammeter, but it applies to most analog meters I've found...
