14. Follow the vehicle manufacturer’s service information for
the proper method to disconnect the fuel line. Special
wrenches or disconnect tools may be required (Fig. 6).
Prop the loose end of the fuel supply line in a position to
prevent fuel from leaking out.
15. Install the appropriate adapter to the fuel line running to
the fuel rail, or directly onto the fuel rail.
Note: If the fuel line connection used by the vehicle
manufacturer is a 3/8” quick-connect style (SAE J2044),
an adapter is not required (Fig. 7).
16. Connect the hose extending from the Cleaner to the
other end of the adapter.
17. Open the inlet valve located between the shop air
connection and the regulator (Fig. 8).
18. Slowly close the air regulator by turning the knob clock-
wise until the pressure gauge reads 5 psi (.3 bar) below
normal operating fuel pressure (Fig. 9).
The value for normal operating fuel pressure can be
located in a service guide or repair manual for the
specific vehicle.
19. Lock the regulator adjustment by pushing in on the knob.
20. Open the outlet valve between the canister and the hose
connection (Fig. 10).
21. Before proceeding:
a. Double check the connections. The Cleaner should
be installed such that the shop air enters the Cleaner,
and cleaning solution flows from the Cleaner into the
fuel rail.
b. Ensure the canister bottle is screwed securely into the
manifold, and is not cross-threaded.
c. Route the Cleaner and shop air hoses, and the
loose end of the fuel supply line away from rotating
engine components, belts, fans, and hot exhaust
components.
d. Remove the fuel spillage rags.
e. Reconnect components such as PCV tubes,
wiring harnesses, vacuum tubes, etc., that were
disconnected to gain access to the fuel line
connection.
