Fit the blanking plugs (B), from the kit (part number 77 01 208 209), on the end pieces of the fuel return pipe. If
Mot.1760 is not fitted immediately on the overpressure valve, place a blanking plug (A) on the overpressure valve
fuel return opening.

IMPORTANT
The end piece is fragile. Be careful not to break it by pulling it too hard. Replace

Fault finding - Tests
Shown above is the pipe (Mot. 1760) with the end piece (2) on the right and the plug (4) on the left.
Remove the clip and the plug from the end piece (2) of the pipe of tool Mot. 1760, leave the plug (4) in place.
Connect the pipe of Mot. 1760 to the rail overpressure valve (without removing the clip on the overpressure valve):
– press on the clip (1) of the overpressure valve,
– insert the end piece (2) in the overpressure valve fuel return opening.
– do not forget to fit the end piece plug (2) to the overpressure valve fuel return opening using the clip supplied.
Remove the plug (4).
Insert the end of the pipe in the measuring cylinder of the tool Mot. 1760, the measuring cylinder is retrieved from
the tool Mot.1711.
Measure the return flow (see the procedure in part 1 of this test).

Part 3: Removing the tool:
Disconnect the pipe of Mot. 1760 on the overpressure valve:
– press on the clip (1) of the overpressure valve,
– pull horizontally on the end piece (2) of the pipe of Mot. 1760 while putting a cloth on the end piece (2) to avoid the
drips.
Lift the end piece (2) vertically so that the diesel fuel contained in the pipe flows into the measuring cylinder of
Mot. 1760.
Remove the plug from the fuel return pipe end piece (2).
Connect the complete fuel return pipe to the overpressure valve.
Wipe up any diesel fuel run-off using a cleaning cloth (part number 77 11 211 707).
TEST6
(CONTINUED 4)
IMPORTANT
Use a cleaning cloth (part number 77 11 211 707) to absorb fuel run-off.
