Complete Tankmaster ‘O’ Ring kit
Contains all 9 ‘O’ Rings used in the Tankmaster Mark I and Mark II.
Note: Not all ‘O’ Rings can be used unless the Tankmaster is completely taken apart, including servicing of the central oil flow control shaft (which is best done in the factory). If you do decide to service the ‘O’ rings on the central control valve then look at the cut away picture of the control valve to establish the correct sequence for reassembly of the spring movement, washers, etc.
Please see the helpful cut-away image of the Tankmaster valve above.
