- Check condition of all hoses and pipes. Remove small vacuum hose from air suction valve "B" and plug hose end. With engine idling, a "bubbling" sound should be heard when air cleaner lid is removed.
- Replace vacuum hose on valve "B". A noise should be heard from inlet pipe of valve within 2-6 seconds after replacing hose. If system operates properly, test is complete. If not, check air suction valve.
- Remove filter and valve from air cleaner housing. No air should pass when blowing into valve pipe. Air should pass if sucking through valve pipe. Reinstall valve and filter.
- Remove air suction valve "B". Check valve by blowing into pipes. With vacuum applied to valve diaphragm, air should flow from filter side to air cleaner side and not the other way. With no vacuum, air should not flow from filter side to outlet side. Reinstall valve.
