SUBJECT:
INFORMATION ON INSTALLATION OF CPI FUEL LINE CLIPS
MODELS:
1992-93 S/T AND M/L MODELS WITH 4.3L ENGINES (RPO L35)
Improper installation of the fuel line clips which hold the fuel inlet and outlet tubes to the Central Port Fuel Injection (CPI) unit may result in an internal
CPI fuel leak. A fuel leak may cause driveability problems or in extreme cases, hydrolock.
Proper Removal and Installation of Fuel Line Clips:
Removal
Using needle nose pliers, firmly grasp the fuel fitting clip as shown in Figure 1 and pull the clip straight back from the fuel meter body. It may be
necessary to lift the opposite side of the clip with a screwdriver. Discard the clip.
Installation
Always use a new clip and 0-rings (P/N 17112702). Using your fingers as shown in Figure 2, slide the clip over the fuel meter body making sure that the
clip properly engages the slots in the fuel inlet and outlet tubes and that the clip is properly positioned over the fuel meter body on both the top and
bottom sides. The clip will be properly positioned when the flanges on the fuel meter body protrude from the clip and the clip snaps in place.
Important
Do not install the clip from the bottom-up position, the clip will not properly retain the fuel lines. Install the clip from the top-down position as
shown in Figure 2. Secondly, it is important to note that the fuel lines MUST be in the correct inlet/outlet openings (The lines will fit either opening).
Lastly, the fuel lines MUST be correctly seated into the TB body to allow for proper installation of the clips.
