5) With the stopper assembly in place,

the weighted pick-up should rest away from

therear of the tank and move freely inside the

tank. The top of the vent tube should rest just

below the top of the tank. It should not touch

the top of the tank.

6) When satisfied with the alignment of

the stopper assembly tighten the 3 x 20mm

machine screw until the rubber stopper ex-

pands and seals the tank opening. Do not

overtighten the assembly as this could cause

the tank to split.

3) Carefully bend the second nylon tube

up at a 45º angle. This tube is the vent tube.

4) 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 falls into the tank.

You should mark which tube is the vent

and which is the fuel pickup when you attach

fuel tubing to the tubes in the stopper. Once

thetankis installed inside the fuselage, it may

be difficult to determine which is which.

firewall.
