I just re-read my post #9 and realized the wording was confusing. When you took this 139.9 Ohm measurement, did you disconnect the tan wire from the sending unit and then measure the resistance between the sending unit electrical terminal post and the metal fuel line on the sending unit? I'm looking for the internal resistance of the sending unit that is currently installed in your truck.
