[TR] Fuel gage / sending unit issue - Spit bodied GT6

[aribert neumann]

Greetings all.   Long time since I've posted, my car has, up till
yesterday, been behaving itself nicely.   Yesterday the driver's door glass
dropped off of the window regulator as I was trying to wind up the window
prior to backing out of the garage.  Then later the same day the fuel gauge
suddenly displayed well past a full tank.  The tank is at about 1/3 to 1/2
full.

The water temp gauge is reading correctly so I am thinking the bimetal
voltage stabilizer is OK.  I checked the connections at both the tank and
gage.  I checked that the ground lead at the tank was grounded.   I am
measuring about 67ohm across the sending unit terminals.   The Bently
manual is worthless on this subject - simply stating that there is no
repair to either gage or sending unit and replacement is the repair
method.  No resistance values given for empty and full tank.  Frustrating.
Before I order a fuel tank sending unit, does anyone know what the ballpark
resistance values might be?   What am I forgetting to check?

TIA.   Off in digest mode awaiting your answers.
