Refueling Control Valve

NOTE: On Frontier, Maxima, Sentra and Xterra, refueling control valve is not replaceable. If defective, fuel tank must be replaced.

Remove fuel filler cap. Check air continuity between hose ends "A" and "B". Blow air into hose end "B". See Figure or Figure . Air should flow freely into fuel tank. Blow air into hose "A". Air should not flow. Using a hand pressure pump with a vacuum "T", apply 2.9 psi (20 kPa) of pressure to hoses "A" and "B". Air should not escape. If operation is not as specified, replace fuel tank with refueling control valve. If operation is as specified, refueling control valve is okay.
