The fuel supply systemA fuel supply system has a fuel tank, a
fuel pipeline and a pump. Fuel moves along the pipeline to the
carburettor or the fuel injector. These supply the engines
cylinders with a mixture of fuel and air. The diagram shows one
possible layout of a fuel supply system.
The metal or plastic fuel tank is at the rear of the vehicle. It
is lled through a fuel supply pipe, closed by a fi ller cap. A fi
lter around the outlet pipe from the tank removes dirt and water
from the fuel. Fuel passes through a metal or plastic pipeline to
the front of the vehicle. This pipeline is xed with clamps to the
chassis.
When the engine is running, it moves on exible mountings.
Therefore it must have a exible fuel pipe. The xed pipeline is
connected to a fl exible pipe, made of plastic, which carries fuel
to the pump. Both the pump and the carburettor are xed to the
engine. The engine drives the pump, which pumps fuel into the
carburettor.
The fuel pipeline is suspended from the chassis.
