Install bowl cover gasket, install needle in seat, then install float and
lever assembly. (Do not forget pin and spring in spring-loaded needle.)

surface of casting. Correct setting is 3/8" on 444S, 1/4" on 453S,
with needle seated. (Use tool T109-80.) Adjustment is obtained by bending
the lip on float which contacts needle. Do not bend on front of float in
adjusting, as damage will result. When holding bowl cover in normal position,
free end of float should have minimum drop of 1/2". Adjustment can be
made by bending two small float-stop lips at anchored end of float.
Note: When setting float in units with spring-loaded needle do not depress
lip against spring in needle, but let float hang of its own weight. Gauge
should barely touch float.
