FUEL TANK
The fuel tank is located under the rear of the vehicle. The fuel pump
and fuel level gauge are installed on the upper part of fuel tank.
Whenever servicing the fuel level gauge or the fuel pump, the fuel
tank must be removed from the body.
FUEL FILTER
The fuel filter is located in front of fuel tank as shown in figure and
filters the fuel sent under pressure from the fuel pump.
As it can’t be disassembled, it must be replaced as an assembly.
FUEL FILLER CAP
A ratchet tightening device on the threaded fuel filler cap reduces
the chances of incorrect installation, which would prevent sealing
fuel vapors.
After the gasket (2) on fuel filler cap and the filler neck flange con-
tact, the ratchet produces a loud clicking noise, indicating the seal
has been set.
This cap has a vacuum relief valve (1) inside.
The vacuum relief valve opens to relieve the vacuum created in the
fuel tank (supplies air (3) into tank).
