Sending unit refurb?

repops are $30 on Ebay. I got one and would test it for you but I installed in 2 weeks ago. Have not tried it yet. Not sure if it used generic GM Ohms or Chrysler....wasn't that important to me at the time, been driving a company truck for 3 years with no gas guage now. Odometer hits 250 and im looking for gas.
