7. Fuel System
7.1 Fuel System Overview
W WARNING!
Fuel is flammable; keep naked flames away from the fuel system. Stop the engine immediately if
a fuel leak is suspected. Do not smoke while refuelling or working on the fuel system. Do not
refuel with the engine running. Completely wipe off any spilt fuel which could cause a fire. There
could be a fire and injury if you do not follow these precautions.
C NOTICE! Do not allow the engine to run out of fuel. If you do not follow these
instructions it could seriously damage the fuel injection equipment and may
be expensive to repair.
C NOTICE! Do not allow dirt to enter the fuel system. Before you disconnect
any part of the fuel system, thoroughly clean around the connection. When a
component has been disconnected, for example a fuel pipe, always fit
protective caps and plugs to prevent dirt ingress. If you do not follow these
instructions it will lead to dirt entering the fuel system. Dirt in the fuel system
will seriously damage the fuel injection equipment and may be expensive to
repair.
The fuel system included on the JCB EcoMAX engine meets the required legislated emission
standards.
The engine needs a supply of clean fuel and a return line back to the fuel tank. The system
is designed to allow high bypass fuel flow and can deliver full flow return to tank.
Materials used for all components and pipe fittings in the fuel system must be resistant to
Diesel fuel. Copper, bronze, brass, tin, lead and zinc coatings can cause deposit formations
which will damage components in the fuel system and therefore must not be used.
Parts of the fuel system which the engine installer needs to provide are normally the
following:
Fuel tank
Fuel feed hoses and pipework
Pre fuel filtration and water agglomerator
Fuel return to fuel tank
The OEM must make sure that these parts are adequately earthed to prevent the build-up of
static electricity.
The OEM must test the fuel system to make sure that it meets the performance requirements
for depression at lift pump inlet, fuel return backpressure and fuel temperature (see the
Technical Data Sheet).
