Fuel Filtering
Refer to the engine user and service manual for the type of filtering provided with the
engine. Depending on the operating environment, additional filtration may be required.
If the fuel has a high water content, or if temperature fluctuations produce water
condensation in the tank, a water separator is required in the fuel supply line.
If the vehicle will be operated under extreme conditions (poor fuel quality, dirt contamination
of fuel likely, high water content, poor access to spare filters) it is strongly recommended
that a combination of strainers and filters be used in the supply line.
Fuel Tanks
The basic requirements for tanks are:
•
Tanks must be ventilated adequately at any angle the engine may operate in.
•
Tanks must not be galvanized with zinc or made of any metal high in zinc because
some fuels will react with the tank and build up a soapy zinc compound that clogs the
fuel injectors.
•
Tanks must be constructed to have a large surface area at any fuel level to facilitate
outgassing.
•
Tanks must have a sludge drain valve at the bottom.
Supply and Return Fuel Lines for Fuel Injection
•
Metal lines must be non-scaling.
•
If the lines are not metal, the material must be heat-resistant (to 100°C).
•
Line runs must be as straight and short as possible between tank and inlets or
outlets.
•
The return line must not be connected to the supply line. It must return fuel to the
tank.
