| (2) BRAKE LEVER. We suggest that it may be possible to cheapen the pawl and trigger mechanism. PETROL TANK FILTER. We suggest that we reconsider the design of the two level device and that a single large filter might be more economical if equally efficient. With the use of the edge filter to remove water it may be that the filter could have gauze of coarser mesh and so be less liable to need cleaning. AUTOVAC TANK. We suggest that with the Enot's filter we may not need the sump and drain on the autovac tank provided the pipe goes from the base of the tank, the filter chamber acting as a sump. WIRING. We suggest that all reasonably likely wires be included in the conduits which we suggest should be large so that any change in the wiring does not scrap the tube and conduit sizes.
