❑ Push the two aluminum tubes through the rubber stopper.
❑ Slide the large diameter metal plate over the tubes at the front of the
rubber stopper, and slide the small diameter metal plate over the tubes at
the rear of the rubber stopper.
❑ Measure the distance that the two aluminum tubes protrude from the front
of the stopper assembly. This distance should be 3/8" (10mm).
❑ Carefully bend the longer of the two aluminum tubes up at a shallow
angle, being careful not to kink the tubing as you bend it.
IMPORTANT When the stopper assembly is installed in the fuel tank,
the top of the vent tube (the tube you just bent) should rest just below the
top of the fuel tank. the top of the fuel tank is a shorter distance from
the fuel tank opening than the bottom is.
❑ Secure one end of the silicone fuel tubing onto the end of the clunk.
❑ Slide the silicone fuel tubing, with the clunk attached, onto the end of the
aluminum fuel pick-up tube (straight tube). Adjust the length of the silicone
tubing until the end of the clunk is 3-1/4" (83mm) back from the rear of the
stopper assembly.
❑ Push the metal neck-reinforcement ring over the neck of the fuel tank
opening, then carefully push the stopper assembly into the fuel tank and rotate
it until the aluminum vent tube rests just below the top of the fuel tank.
