FUEL SYSTEM TROUBLE IN GENERAL
26.Fuel System Trouble in General
A: INSPECTION
NOTE:
• When the vehicle is left unattended for an ex-
tended period of time, water may accumulate in the
fuel tank.
To prevent water condensation.
(1) Top off the fuel tank or drain the fuel com-
pletely.
(2) Drain water condensation from the fuel filter.
• Refilling the fuel tank.
Refill the fuel tank while there is still some fuel left in
the tank.
• Protecting the fuel system against freezing and
water condensation.
(3) Cold areas
In snow-covered areas, mountainous areas, ski-
ing areas, etc. where ambient temperatures
drop below 0
°
C (32
°
F) throughout the winter
season, use an anti-freeze solution in the cool-
ing system. Refueling will also complement the
effect of anti-freeze solution each time the fuel
level drops to about one-half. After the winter
season, drain water which may have accumulat-
ed in the fuel filter and fuel tank in the manner
same as that described under “Affected areas”
below.
(4) Affected areas
When water condensation is notched in the fuel
filter, drain water from both the fuel filter and fuel
tank or use a water removing agent (or anti-
freeze solution) in the fuel tank.
• Observe the instructions, notes, etc., indicated
on the label affixed to the anti-freeze solution (wa-
ter removing agent) container before use.
