ORVR Vent Shut Valve Test
Float Test
1. Make sure the fuel tank is less than half full.
2. Remove the fuel fill cap to relieve the fuel tank pres-
sure, then reinstall the cap.
3. Remove the fuel hose joint protector. Disconnect
the ORVR vapor recirculation hose, and connect a
vacuum pump to the vapor recirculation hose.
ORVR VAPOERECIRCULATION
VACUUM PUMP/GAUGE,0 - 30 in.H9A973X - 041 -
xxxxx
Plug the hose port.
Apply vacuum to the ORVR vapor recirculation
nose.
. lf the vacuum holds, replace the ORVR vent shut
valve {see page 11-297).
. lf the vacuum does not hold, the float is OK.

1. Make sure the fueltank is lessthan halffull.
2. Remove the fuel fill cap.
3. Remove the fuel hose joint protector. Disconnect the
ORVR signal hose.
ORVRSIGNALHOSE
Disconnect the vacuum hose from the EVAP control
canister. and then plug the port with a plug.

CONTROLCANISTERVENT SHUTVALVE
Disconnect the vacuum hose from the EVAP control
canister vent shut valve, and connect a vacuum pump
to the vacuum hose,
Pump the vacuum pump 80 times.. lf the vacuum holds, go to step 7,. lf thevacuum does not hold, goto step9.
