Hi Tim – I think it’s Tim, checking on your membership number. There now seem to be a load of cheap Chinese sender units with a skewered float on ebay, Cheap enough to keep the float and throw away the rest – like https://www.ebay.co.uk/itm/402259541854. You might have to straighten out the end of the sender arm a bit to fit in the float though.
