Hi Phil ,ref the electrics I am waiting to get my tinware back then once the motor is in I will see if it all works,but I can't find any mission electrical points where a wire with ring connectors on each end would need to be . It might be left over from the previous 1915 motor or the turbo motor that was in it .so it may well have not been connected on one end ? Just can't remember. The rubber bush looks like it was screwed to the triangular support shown in the pic with that screw in the same place as the battery Earth on the opposite side .as for the filter it is the stepped type and so the clamp is on the right area but didn't know that it should be on the other side of the fire wall ?
