Fuel Injector (3.9L/5.2L/5.9L TBI Models): Installation

Install lower "O" ring on injector. "O" ring should butt against plastic filter assembly. Inspect both "O" rings for cuts or tears and replace if necessary. Align injector terminal housing with locating socket in injector cap.
Press injector into cap so that upper "O" ring flange is flush with lower surface of cap. Spray inner surfaces of injector pod with Mopar Brake and Carburetor Parts Cleaner or equivalent to remove residual gasoline.
Lightly lubricate upper and lower "O" rings with petroleum jelly. Place injector and cap in injector pod and align cap locating pin with locating hole in casting. See Figure.
CAUTION: Passenger side cap locating pin is 5 mm in diameter and will only fit in passenger side locating hole. Driver's side locating pin is 4 mm in diameter.
Repeat steps 1-3 for other injector and cap. Press firmly on injector caps until flush with casting surface. Place injector hold-down clamp with spacer on rear portion of caps, aligning holes in clamp with pins on caps. Install clamp screw. Be sure spacer is in place.
CAUTION: Because "O" ring squeeze may cause caps to lift up, press firmly on both caps with one hand to ensure caps are flush while installing clamp screw.
Tighten screw to 35 INCH lbs. (4 N.m). Connect negative battery cable. Pressure test system for leaks. Reinstall air cleaner assembly.
