Test fit the stopper assembly into the tank. It may
be necessary to remove some of the flashing around
the tank opening using a modeling knife. If flashing is
present, make sure none of it falls into the tank.
6)
When satisfied with the alignment of the stopper
assembly tighten the 3mm x 20mm machine screw until
the rubber stopper expands and seals the tank opening.
Do not over tighten the assembly as this could cause
the tank to split.
7)
Using a modeling knife, cut 3 lengths of fuel line
150mm long. Connect 2 lines to the 2 vent tubes and 1
line to the fuel pickup tube in the stopper.
8)
Feed three lines through the fuel tank compart-
