- Carefully bend the second nylon tube up at a 45º
angle. his tube is the vent tube.
- Test it the stopper assembly into the tank. It
may be necessary to remove some of the lashing
around the tank opening using a modeling knife.
If lashing is present, make sure none falls into the
tank.
- With the stopper assembly in place, the weighted
pick-up should rest away from the rear of the tank
and move freely inside the tank. he top of the vent
tube should rest just below the top of the tank. It
should not touch the top of the tank.
- When satisied with the alignment of the stopper
assembly tighten the 3 x 20mm machine screw un-
til the rubber stopper expands and seals the tank
opening. Do not overtighten the assembly as this
could cause the tank to split.
