together
4 Tap the element on a hard surface to dislodge
any large particles of dirt, then if compressed air
is available, use it to clean the element, directing
the air from the inside out (see illustration).
5 Check the element for signs of damage. If the
element is torn or cannot be cleaned, or is
obviously beyond further use, renew it.
6 Install the filter element, making sure it is
properly seated, and install the fuel tank (see
Chapter 4).
Caution: If the machine is ridden in dusty
conditions, the filter should be cleaned more
frequently.
A Warning: Petrol (gasoline) is
extremely flammable, so take extra
precautions when you work on any
part of the fuel system. Don't smoke
or allow open flames or bare light bulbs near
the work area, and don't work in a garage
where a natural gas-type appliance is present.
If you spill any fuel on your skin, rinse it off
immediately with soap and water. When you
perform any kind of work on the fuel system,
wear safety glasses and have a fire
extinguisher suitable for a Class B type fire
(flammable liquids) on hand.

Check
1 Remove the fuel tank (see Chapter 4) and
check the tank, the fuel tap, the fuel pump and
the fuel and vacuum hoses for signs of leakage,
deterioration or damage; in particular check that
there is no leakage from the fuel hoses. Renew
any hoses which are cracked or deteriorated.
2 If the fuel tap is leaking, tighten the assembly
screws (see Chapter 4). If leakage persists
remove the screws and disassemble the tap,
noting how the components fit. Inspect all
components and renew any that are worn or
damaged. Some components are available
individually, though it may be necessary to renew
the whole tap, depending on your model.
3 If the carburettor gaskets are leaking, the
carburettors should be disassembled and rebuilt
using new gaskets and seals (see Chapter 4).

Filter cleaning

4 Cleaning or renewal of the fuel filter is advised
after a particularly high mileage has been
covered. It is also necessary if fuel starvation is
suspected.
5 On TRX, XTZ and 1991 to 1998 TDM models,
the fuel filters are mounted in the tank. On TDM
models, the filters are integral with the fuel outlet
assembly from the tank. On TRX and XTZ
models, the filters are integral with the fuel tap.
On XTZ models, each fuel tap has its own filter.

Clean the gauze filter to remove all traces of dirt
and fuel sediment. Check the gauze for holes. If
any are found, a new filter should be fitted (check
for availability - it may be necessary to renew the
whole tap). Check the condition of the O-ring and
renew it if it is in any way damaged or
deteriorated. 6 On 1999 TDM models and in-line
fuel filter is fitted between the fuel tap and fuel
pump. Refer to Section 23 for details.
