FUEL FILTER MAINTENANCE
Kubota fuel systems will be designed with a
specification, which requires filtration of the system. With
the EControls designed fuel system; the filter have been
attached with additional filtration, (Refer to Kubota Base
engine section).
To determine the recommended maintenance
intervals,
refer
to
the EControls
Maintenance Schedule at the end of this section.
However, engines which operate in extremely dirty
environment will require more frequent maintenance.
When inspecting the fuel filtration systems, check
the following:
• Check for any fuel leaks at the inlet and outlet
fittings.
• Check to make sure the filter is securely mounted.
• Check for any external damage or distortion; if
damaged replace the filter element.
To replace the filters use the following steps:
1. Move the equipment to a well ventilated area and
insure there are no external ignition sources.
2. On LPG / Natural Gas systems start the engine and
close the manual valve on the cylinder, and run the
engine until the engine runs out of fuel.
3. Remove and replace the fuel filter.
4. Leak check the connections with a soapy solution, or
electronic leak detector.
5. On Gasoline fuel pumps with integrated fuel filters or
screens located in the tank, follow the procedures for
pump removal.
6. On externally mounted filters, close the manual valve
at the gasoline tank to prevent fuel from draining
from the tank.
7. Drain any excess fuel into an approved container
and replace the filter.
8. After replacing the filter, start the engine and leak
check all connections.
WARNING
ALWAYS WEAR PROTECTIVE EYEWEAR AND GLOVES WHEN
PERFORMING MAINTENANCE ON THE LPG / NATURAL GAS
OR GASOLINE FUEL SYSTEMS, TO PREVENT SERIOUS
INJURY. ALWAYS PERFORM MAINTENANCE PROCEDURES

ARE NO EXTERNAL SOURCES OF IGNITION
FUEL SUPPLY AND RETURN LINE MAINTENANCE
Kubota LPG / Natural Gas and Gasoline fuel system
utilize fuel supply and return lines that are attached by
Kubota. These lines are made of special rubber or metal
material, which meet the design working pressures,
regional requirements, and provide the proper protection
from chemicals found in the fuels. It is recommended
Recommended
that all the fuel line connections be leak checked
annually at a minimum, or anytime the lines have been
removed. The routing of the lines should also be
inspected annually, to insure that the lines have not
come into contact with any rotating devices, hot
surfaces, or are located in a position in which they may
be impacted by debris.
