Part 2: Fitting the tool:
Remove the engine undertray.
Disconnect the overpressure valve return pipe according to the following procedure (do not remove the clips):
– press the clip,
– pull vertically on the end piece (1) of the fuel return pipe.

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

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).
