This is a spill-over from the fuel gauge anti-slosh thread.

In the meantime I dug out 3 old senders and I put together a test rig to check the calibration of them. Two of the senders were junk so I cut them up to see how they worked. Oil pressure moves the copper diaphragm which acts on a button with a linkage which swings a wiper arm over rheostat type arrangement. The pictures show the parts for the sender. In the out of focus shot I am pushing on the button to move the wiper to the mid position. The last shot is of the test rig that uses parts from a fuel injection test kit. The pressure source is my compressor.
I will post information about the gauges when I have tested them.

Rich and I had a conversation yesterday evening. He will send me Spider and GTV oil pressure gauges and I will determine what electrical signals they need from the sender.Finally, i know (i think) that with oil pressure some sending units work in reverse.
I didn't mean to hijack this thread - would it be better to start a new one? For that matter Ed, is this something you have the time and interest in doing. I'm happy to share the cost...
