I need some fuel sending unit experts please

10 ohm resistor between the Oil pressure gage connector and ground should bring the gage to H or approximately 80 psi
22 ohms resistance should bring the pressure gage to show middle, and anything over 75 it should show zero.
So either high resistance or no connection would keep the pressure gage from working.

PS. Like the fuel gages, replacement oil pressure senders aren't matched to the '60s gages.

Here are the readings I got on fuel with tank almost empty:

Key off sending unit to ground - 62 ohms

Key on sending unit connector to ground. Video of V and Ohms ( not sure if the video will work)

As far as the oil pressure sender. Except for connector to gauge, which has continuity, everything reads open.

Sender to connector - open. Sender connector to ground - open. Sender to ground open. Even the body of sending unit to ground shows open.
