The fuel pump module includes the regulator for the
non-return fuel supply, and fuel tank pressure sensor
(FTPS). Also added in the tank are: fuel filler line
leading to an in-tank one-way check valve at the base
of the tank to reduce rollover spillage. Fill vent vapor
separator valve to decrease vapor leak, and a new
ORVR control valve to reduce fuel vapor emissions
during refueling. These have all been moved to inside
the tank to decrease hydrocarbon vapor leak.
A new style fuel cap for Kia will be used. This is the
return fuel cap, designed to prevent cross threading
when installing the cap after refueling. Insert fuel cap
into the fuel filler neck and turn 1/4 turn clockwise,
then turn until clicks are heard.
A new Auxiliary Canister has been added to decrease
bleed emissions and works in conjunction with the
evaporative canister; both are located to the rear right
side of the fuel tank. A vapor hose runs from the main
canister to the auxiliary canister.
The evaporative flexible fuel vapor lines have been
changed to a 3-ply design. 3-ply hose must be used
when replacing, and the number of hose joints has
been reduced — both to reduce HC evaporative
emissions.
