7.2.4 Fuel Filters and Water Separators
A machine-mounted electric lift pump, fuel pre-filter and water agglomerator is supplied loose
with the engine. The OEM must install this onto the equipment chassis, close to the engine
and in a warm position. However not adjacent to the exhaust system. The efficiency of the
water separation must be a minimum of 95% (measured to SAE J1839).
This electric lift pump filter unit includes a water presence detector which must be connected
to the engine control unit. The positive feed to the water in fuel sensor must come from the
ignition relay. The electric lift pump must also be connected to the appropriate relay
controlled by the engine control unit.
Install the agglomerator above the maximum fill level of the tank to avoid fuel syphoning
when servicing.
Fit a strainer or gauze to the filler neck of the fuel tank to stop large items blocking the fuel
feed pipes.
Water separation requirements vary depending on fuel quality. If the fuel does not comply
with EN590 you may need to install an additional water separator. JCB Power Systems
Applications Department can give advice on expected regional fuel conditions.
N NOTE: If the fuel temperature drops below the cloud point then fuel filters may
become blocked.
