WARNING:
DIESEL FUEL IS HARMFUL TO SKIN. MAKE SURE THE RELEVANT PERSONAL
PROTECTION EQUIPMENT IS WORN.
•
Ensure the main fuel tank is clear of dirt and water.
•
A separate water trap must be fitted to all engine installations. The Shire 43 WB & 49
WB engines are supplied with an additional fuel pre-filter water trap as standard.
•
Connect fuel feed return hoses from engine to main supply and return lines to main
fuel tank, ensuring they are connected the correct way around. The hose to the electric
fuel pump is the inlet.
•
The engine hoses are supplied with 5/16” (8mm) OD metal hosetails and should be
securely fitted to the main supply and return pipes with compression fittings.
•
The engine hoses should have sufficient slack to absorb engine movement without
placing strain on the hoses and be securely clipped to prevent accidental damage and
chafing.
•
Initially fill the fuel system by turning the ignition on to operate the electric fuel pump.
Loosen the bleed screw on the top of the primary fuel filter / water trap, followed by
the secondary fuel filter and close when fuel begins to flow clearly (no bubbles). The
rest of the process is done automatically by the engine. It is rarely necessary to bleed
the injection pump or injectors upon installation as the engine will already have fuel in
it from the engine run in and test procedure.
•
If the engine completely runs out of fuel, the injectors will require bleeding.
12. Coolant
WARNING:
SCALD HAZARD!
NEVER REMOVE THE COOLANT BOTTLE CAP IF THE ENGINE IS
HOT. STEAM AND HOT COOLANT WILL SPURT OUT AND CAUSE INJURY. TIGHTEN
THE CAP SECURELY AFTER BEING REMOVED. STEAM MAY SPURT OUT DURING
ENGINE OPERATION IF THE CAP IS LOOSE.
