1. Wipe clean valvehousing.

4.
Suck airthrough thecap. Aslight resistance accompanied
by valve clicks indicates thatvalve Ais ingood mechanical
condition. Notealsothat, byfurther sucking air,the resis-
tance should disappear withvalve clicks.
3. Blow aironfuel tank sideandensure thatcontinuity ofair
