Fuel Injector - Installation
Prior to installation of the fuel injector, make sure all mating
surfaces are clean, dry and free from contamination.
1. Install fuel injector O-ring, if not already installed (
A
,
43
2. Lubricate the O-Ring with clean engine oil.
3. Install the fuel injector into the throttle body housing by
pushing the injector into the housing until both mating
surfaces meet. Rotate, if necessary, the injector so that
the mounting bracket holes align with the mounting holes
on the throttle body.
NOTE:
Make sure the fuel injector is orientated in the correct
direction. The two fuel line ports should face the engine valve
cover.
4. Install the two fuel injector mounting bolts (
E
, Figure 42).
Tighten to
13 lb-in
(1.5 Nm).
5. Install the two fuel lines on the fuel injector. Make sure
that the supply and return lines are connected to the
correct injector port, as indicated by arrows stamped on
the injector.
NOTE:
The fuel line that connects the fuel injector to the fuel
pump is the supply line. The fuel line that connects the fuel
injector to the fuel tank is the return line.
6. Install the two fuel line clamps by squeezing the tangs
and sliding the clamps along the fuel line until they are in
the correct position. Position the clamps
1/8 inch
(3 mm)
from the end of the fuel lines (
D

connector will "click" when fully installed (
