High quality Fuel sender unit TR2 to 3B. The float arm of this sender unit can be adjusted for height and reach to suit various tank dimensions.The mounting plate of this unit has the normal 6 screw attachment to suit the TR fuel tank.

This sender unit should be considers whether you have a standard tank or an extra capacity tank as you will enjoy the benefits of more accurate fuel tank contents reading on your fuel gauge. This high quality part is far more stable, giving more acurate readings and has a higher longevity expectation than the standard aftermarket replacement TR2-3B units part numbers 202137 and 203610 currently available.

The characteristics of this sender unit can be varied in two ways. The top mounting plate has attached to it a vertical post to which the resistor pack with its moving arm can be slid up and down to position it at various locations. This adjustment will take account of various tank depths. Secondly the length of the swinging arm with the float on it can be varied to ensure full and empty readings are accurate. In the photograph the parts are shown disassembled, they are assembled on installation at which time the position of the resistor pack and float are set in accordance with a chart and full instructions supplied with the kit.

For reference the resistance range of this sender unit will nominally read 3 Ohms empty to 80 Ohms full and is therefore suitable to drive all TR2-3B standard original Moving Iron fuel gauges gauges with a part number on the face starting FG or PG, as well as our range of replacement new gauges for these cars which require the same resistive range sender unit. The unit can of course be used to drive any fuel gauge designed to operate with a sender unit with the resistive range mentioned above.  

Later TR4-6 gauges are of the 'BiMetal' type requiring part number RTR8514-1 which is a similar unit with a different resister pack.

This sender unit RTR8514 is included in our TR2-3B new fuel gauge and sender package part number RTR8564NK.
