Carved top fuel inlet port to proper dimension. Sanded internal and external of tank where o-ring fittings pass. This is to insure a fluid tite seal. We will see. Formed the supplied 1" aluminum strapping material to conform to the tank contours. Positioned tank on seat frame and drilled the four 3/16" holes to secure the tank. One addition was to place a adhesive backed 1" felt cushion strip on the back of the strapping.
