Fuel Filler Cap: Description and Operation
DESCRIPTION AND OPERATION
WARNING: Fuel tank may be pressurized. To remove, rotate cap over 1/2 turn counterclockwise. If cap is venting fuel or a hissing
sound is heard, wait until the condition stops before removing the cap. If these precautions are not followed, fuel may spray and cause
personal injury.
The fuel cap is of a threaded screw-on design with a pre-vent feature that allows the tank to vent for the first three-quarter turn before unthreading.
All fuel caps are attached to the vehicle with a tether using the filler pipe-to-housing screw at the three to four o'clock position. The fuel cap
assembly provides pressure and vacuum relief functions, and should be replaced with the proper pressure/vacuum relief cap to prevent possible
system malfunction.
WARNING: Do not smoke, carry lighted tobacco or an open flame of any type when working on or near any fuel-related component.
Highly flammable mixtures are always present and may be ignited, resulting in possible personal injury.
