Measuring to fit the tail lights properly. Notice the clear lens to more closely match the (ultimate) white paint. (I had to slightly modify the tail lights to pass inspection, but I think I still preserved the 'clear' effect).
Two on top left hold float to proper height; two lower left are for measuring float level. Top right is tang-bending tool, lower right is to measure fuel inlet needle setting. (center tools perform same functions as the two on left, just slightly different designs).
