then remove the sipper by sliding it straight out of the mounts.
Carefully insert the long thin end of the new sipper and slide it into the mounts. Slide the sipper cone up the sipper and
screw it into the sipper arm. Be sure the sipper is centered in both mounts. Tighten the mount screws gently until they
contact the sipper, then tighten an additional ¼ turn (
do not over tighten ). Install the sipper arm cover and secure using
the hex screw ( do not over tighten ).
Route the new sipper tubing behind the sipper assembly and connect the other end to the front connector of the sipper
pump.
