– Read off fuel pressure at K-Jetronic pressure tester -V.A.G
1318- .
• Specification: 5 to 8 bar
– Stop procedure once fuel pressure no longer rises at K-Jet‐
ronic pressure tester -V.A.G 1318- .
If the specification is not attained:
– Checking fuel pump delivery rate ⇒ Rep. gr. 20
Checking holding pressure
– Check for leaks and check holding pressure by observing
pressure drop at K-Jetronic pressure tester -V.A.G 1318- .
• After 10 minutes, there must be a residual pressure of at least
3 bar.
If the holding pressure drops below 3 bar:
♦ Check threaded connection between pressure gauge and fuel
line for leaks.
♦ Check pressure gauge for leaks.
♦ Check fuel lines and their connections for leaks.
♦ Checking fuel pump delivery rate ⇒ Rep. gr. 20
♦ Renew fuel filter with integrated fuel pressure regulator ⇒ Rep.
gr. 20 .
♦ Fuel pump non-return valve is defective ⇒ Rep. gr. 20 .
Assembly is carried out in the reverse order. When installing, note
the following:
– Switch off ignition.
Note
Fuel pressure must be reduced by opening shut-off valve before
removing pressure tester. Hold collecting container at connection
as you do so.
