eral Procedures

1.
WARNING: BEFORE PROCEEDING, IT IS ESSENTIAL THAT
THE WARNING NOTES GIVEN IN SECTION 100-00 (UNDER THE
HEADING 'SAFETY PRECAUTIONS') ARE READ AND
UNDERSTOOD.
Remove the battery. Refer to operation 86.15.01.

2. De
pressurise the fuel system.
E

nsure that the ignition is
switched off and remove the
valve cap from the fuel cross-over pipe. Place a cloth
under the valve to collect any spillage.
Pla
ce a closed container, su
itable for collecting fuel,
adjacent to the vehicle. Remove the lid.

3. Conne
ct the fuel injection pressu
re test equipment JD 209 (or
other suitable type). Insert the drain / bleed tube into the fuel
container. Follow the manufa cturer's instructions and
depressurise the fuel system.
4. Store the drained fuel safely and ensure that the lid is closed
securely. Remove the equipmen t and discard the cloth from
beneath the valve. Refit the valve cap.
5. Use a suitable fuel storage tank er / pump system to drain the
vehicle tank as described below.
6. Connect a ground cable betw een the vehicle and drain
equipment and connect both to a suitable earth point.

7. At the engine bay bulkhead, lo cate the quick fit connecto
r
between the underfloor fuel feed pipe and the fuel pulse
damper.
Pla
ce a cloth under the pipes
to absorb any spillage.
D
isconnect the fuel feed hose
at the quick fit connector,
using special tool JD 182.
Conne
ct the fuel drain equipment to the underfloor fuel
feed pipe.
8. Drain the fuel tank in accordance with the equipment
manufacturers instructions.
