WARNING
!
Do not allow smoking or the use of open
flames in the area where work on the fuel or
EVAP system is taking place. Anytime work is
being done on the fuel system, disconnect
the negative battery cable, except for those
tests where battery voltage is required.
1. Disconnect the negative battery cable. Refer to
"Battery Negative Cable Disconnection and
Connection: ".
2. Open the fuel fill door and remove the gas cap.
CAUTION
!
Do not attempt to insert any other type of
siphon hose or tube into the fuel filler pipe.
The design of the inlet check valve at the end
of the fuel filler tube restricts the insertion of
a hose and, most importantly, prevents the
removal of this hose. See Fuel Inlet Check
Valve in this section. If the siphon hose
becomes stuck in the check valve, the fuel
filler pipe will not be able to be removed from
the fuel tank without damage to the fill pipe
or fuel tank.
3. Insert the J 42960-2 into the fuel fill pipe.
NOTE
The siphon hose will reach the bottom of the
tank, on the primary side only, within about
25.4 cm (10 in) of the end fitting and tag.
When connecting the siphon hose to another
length of hose connected to the fuel drain
tanker, DO NOT insert the siphon hose into
the fill pipe funnel past the tag at the fitting
end. If inserted too far, the upper portion of
the siphon hose may pass through the check
valve cage and then jam on attempted
removal.
4. Insert the J 45004 into the guide funnel and into the
fuel fill pipe. Some resistance may be encountered
when the tip of the siphon hose reaches the inlet
check valve. Repeated probing may be necessary to
slide the hose tip through the check valve cage.
WARNING
!
Whenever fuel lines are removed, catch fuel
in an approved container. Container opening
must be a minimum of 300 mm (12 in)
diameter to adequately catch the fluid.
NOTE
The fuel flow rate from the siphon hose will
range from 1.1 L/min (0.3 gal/min) up to 3.8 L/
min (1 gal/min), depending on whether it is
gravity siphoned or with an air-powered
pump.
5. Begin the fuel siphoning process. Place the fuel into
an approved fuel container.
6. Remove the siphon hose and the fuel flapper door
holder from the fuel fill pipe after draining is
complete.
