| - 2 - located in the pipe run from the tank to the dash, and has a knob protruding through the floorboards near the change speed gate within easy reach of the driver. This scheme has the advantage of reducing the resistance on the suction side of the electric pump to the minimum and avoiding gas lock. The illumination of the knob at night time also is an advance on what we have now, that is, it is more in the open, and if the indication is made clear enough there may be enough light available for the purpose of showing the driver which is reserve and which is main. If it is considered necessary to bring the control up to the instrument board, this involves using a more complicated scheme. We are starting on Monday our big push on the Wraith and we propose to concentrate on this chassis before modifications come along for the SpectreCodename for Phantom III, with a view to having an experimental Wraith running about by Christmas time.
