SPECIFICATIONS

CONSTRUCTION DIAGRAM

This fuel system is designed with consideration for
global environment protection to ensure safety at a
collision, reduce weight, and improve reliability and
quality. The system has the following features.

• A quick-joint connector of a plastic tube is used

for the fuel high-pressure hoses in the engine
compartment to reduce the permeation of fuel
evaporative emission.

• The surface of underfloor fuel pipes is coated

with 1-mm thickness of plastic to improve resis-
tance to corrosion and chipping.

• The rubber boot is employed for the filler port

mounting part of fuel filler neck to protect fuel filler
neck in case of collision.

The fuel tank assembly consists of the fuel pump
module, fuel level sensor, fuel tank, and others, and
offers the following features.

• The fuel tank is placed under the rear seat floor to

improve the safety upon impact.

• For the fuel tank, pre-coat alloy molten zinc steel

plate is adopted to the tank main body, which
does not contain tin alloy.

• The fuel tank safety valve is integrated in the fuel

tank which prevents fuel leaks when the vehicle
has leaned or rolled over, and a number of open-
ings and pipe joints on the fuel tank upper surface
has been reduced.

• A built-in fuel filter and fuel tank suction hose

have been adopted to offer support to the sad-
dle-type fuel tank.

The fuel pump module consists of the following com-
ponents:

• Fuel pump assembly

• Fuel gauge unit

• Fuel filter

• Fuel tank differential pressure sensor
