FUEL DELIVERY
AIR/FUEL RAIL
Pressure Test
The pressure test will show the available pressure
at the air/fuel rail. It validates the pressure regula-
tor and leaks in the system.
IMPORTANT:
Before checking air/fuel rail pres-
sure, make sure the fuel pressure from the fuel
pump and the air pressure from the air compres-
sor are within specifications. See the procedures
elsewhere in this section.
Also ensure there is no leak from hoses and fit-
tings. Repair any leak.
Ensure there is enough gas in fuel tank.
Release the fuel pressure in the system.
Disconnect outlet hose (the one with the fuel fil-
ter) from fuel pump using tool (P/N 529 035 714).
Connect adapter to pressure gauge as shown.
1. Pressure gauge (P/N 529 035709)
2. T-adapter (P/N 529 035 710)
Install pressure gauge between disconnected
hose (inline installation).
1. Fuel filter
2. Fuel line going to air/fuel rail
3. Pressure gauge between disconnected hose (inline installation)
Install safety lanyard and observe fuel pressure.
Do not crank engine
.
If pressure is within limits, air/fuel rail is working
adequately.
A rapid pressure fall indicates excessive leakage
either from the air/fuel rail or from the fuel pump
check valve.
If pressure is not within limits, ensure there is no
air/fuel leak between direct injector and air/fuel
rail. Otherwise, replace the air/fuel rail as an as-
sembly (rail, air and fuel regulators and fuel injec-
tors).
Remove pressure gauge and reinstall fuel hose.

FUEL REGULATOR PRESSURE
(when installing safety lanyard)
185 ± 14 kPa (27 ± 2 PSI)
WARNING
Wipe off any fuel spillage in the bilge. Fuel is
flammable and explosive under certain con-
ditions. Always work in a well ventilated area.
