I did a lot of research on fuel and temp gauge calibration for my TR4. I've attached a "tech doc" I wrote for our club's newsletter. You might find useful information in it. Good luck!</div>

<b>Subject:</b> [TR] Fuel gage / sending unit issue - Spit bodied GT6</font>
<div> </div>
</div>
<div>
<div dir="ltr">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.
<div><br>
</div>
<div>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? </div>
<div><br>
</div>
<div>TIA. Off in digest mode awaiting your answers.</div>
