NEW FUEL PRESSURE TESTER FOR CIS AND CIS-E FUEL INJECTION SYSTEM
A new 0-10 bar gauge pressure tester is needed for CIS-E fuel injection system pressure checks of 6.2 to 6.4 bar in 116 and 117 engines. This tester is
suitable for all engines equipped with CIS or CIS-E fuel injection Systems.
The existing tester 102 589 00 21 00 can be retrofitted with the 0-10 bar
pressure gauge 103 589 00 21 01.
Note:
An additional adaptor 103 589 02 63 00 is needed for fuel pressure tests in vehicles equipped with two fuel pumps.
