Ohms readings from sending unit...help

I'm trying to sort out my fuel gauge as to why it doesn't work.

Can someone please tell me what setting I should use on the
meter below to read the ohms at my sending unit in the tank.

Also where do I clip the red wire and black wire from the meter?

Everything I have tried only resulted in fluctuating numbers on
the meter that return to zero. I want to make sure my new sending
unit is working correctly before I go any further.

Thank You!
