SERVICE PROCEDURE
IMPORTANT: Follow all warnings, cautions, and notes in the ESM when working on
or near a fuel system and EVAP system components, such as a fuel tank and vent
control valve.
1. Remove the following parts from the vehicle:

Fuel filler pipe

EVAP Canister with vent control valve and EVAP control system pressure sensor
(pressure sensor)

EVAP Canister drain hose(s) and filter (if equipped) that connect to the vent control
valve (Figure 1)

If needed, refer to the Electronic Service Manual (ESM), sections EC-Engine
Control System and FL-Fuel System (as it applies), for removal procedure.
NOTE:
o Remove the fuel filler pipe and fuel filler pipe grommet (grommet) together.
This makes it easier to remove the fuel filler pipe from the vehicle.
o Cover the fuel tank’s rubber filler hose with a clean shop rag or suitable
covering, once the fuel filler pipe has been detached from it.
o The new canister drain hose (drain hose) replaces the drain hose(s) and filter
(if equipped) that connect to the vent control valve (Figure 1). The existing
drain hose(s) and filter are not reinstalled.
Remove these and do not reuse/reinstall
