DESCRIPTION AND OPERATION

--------------------------------------------------------------------------------

Fill Control/Vapor Vent System
Fill control is accomplished through a vent line, attached to the fuel tank
filler pipe (9034) which extends inside the fuel tank (9002) . The fuel vapor
valve (9B593) mounted in top panel of fuel tank and the attached vapor line to
fuel vapor valve , also contribute to fill control by controlling pressure in
the fuel tank when fuel rises to cover the fill vent opening in the fuel tank .
The vent system is designed to provide an air space, approximately 10 percent of
the tank volume, above the fuel level in a full tank. The air space allows for
thermal expansion of fuel and provides clearance between the fuel level and the
fuel vapor valve which is mounted in the top panel of the fuel tank . The
clearance is sufficient to allow vapor venting through the fuel vapor valve
under all static and most dynamic vehicle conditions.

DIAGNOSIS AND TESTING

--------------------------------------------------------------------------------

Diagnosis and Testing
Physical damage, leaks, and missing items are the major answers to diagnosis of
emission system complaints. Damage to the fuel tank filler cap or contamination
that renders the pressure-vacuum valve inoperative may result in deformation of
the fuel tank . Care should always be exercised to make sure a proper fuel tank
filler cap (in working order) is used.

Refer to Powertrain Control/Emissions Diagnosis Manual for individual
components.

You will find any mention for the EVAP system on any routine for drivability or
emission compliance very far down the list, if mentioned at all.
