Honda HR-V: Fuel Supply System Description - Fuel Pump
The fuel tank unit consists of the following components.
2WD
AWD
FUEL SUPPLY SYSTEM DESCRIPTION - JET PUMP (AWD)
Operation
The return fuel entering the jet pump from the fuel pressure regulator passes
through the orifice in the jet pump
to increase the flow speed, which generates increased suction pressure. This
pressure (vacuum pressure) is used
to transport the fuel on the sub fuel tank unit side through the transfer tube
to the main side. A safety valve
(relief valve) is installed for protection of the fuel line in case of an
abnormal fuel pressure rise, caused by a
clogged orifice etc.
FUEL SUPPLY SYSTEM DESCRIPTION - RETURNLESS FUEL SYSTEM
The fuel returnless system incorporates the fuel pressure regulator into the
fuel pump to remove the fuel return
pipe and other parts. The fuel pressure regulator keeps the fuel pressure
constant in the fuel pump to return the
fuel into the fuel tank directly. This does not need the fuel line in the engine
compartment to prevent the fuel
temperature from increasing and to reduce the fuel evaporation of gas in the
fuel tank.
