6. Tighten down the manifold bolts in the proper sequence and torque as recommended in the engine manual.
NOTE: Consult your engine manual for proper fastener torque, bolt tightening pattern and other manifold installation
specifications.
7. Remove the fuel rails. Install the fuel injectors. Lubricate the fuel injector top and bottom O-rings. Do not use synthetic,
animal or vegetable oils. Use of an O-ring specific lubricant is recommended. Use motor oil if you do not have a good
O-ring lubricant. Be careful not to damage the O-rings.
WARNING! Damage of the O-ring can cause fuel leakage. A fuel leak may result in a fire or an explosion hazard, which
could cause serious injury or death.
8. Carefully install the injectors into the rails and then install the injectors and both rails into the manifold. Reinstall the four
1/4-
20 x 1” Allen head screws that held the rails in place and tighten securely.
9. Make sure that the four end fittings in the fuel rails (they should already be installed but not tightened) are threaded in to an
adequate depth.
10. Reattach the front and rear crossover tubes. Tighten completely hand tight.
11. After the crossover tubes are installed, tighten the nut on the four fittings that go into the fuel rails. Tighten securely.
12. Securely tighten the front and rear crossover tubes with a wrench.
13. The regulator should already be installed. Make sure that the two Allen head screws securing it to the fuel rail are tight.
Also check that the regulator fitting it tight and is pointed in the desired direction. Do not overtighten the fitting in the
regulator or it will leak.

14. Next install the throttle body. The throttle body is in a separate box in the kit, which contains the gaskets needed. First
install the gasket that matches the manifold base. Next install the steel plate included with the throttle body. Next install the
gasket that matches the plate. Install the throttle body with the 4 5/16-18 bolts and washers included. The MAP sensor
bracket is attached by the rear, passenger side bolt. Install the MAP sensor first with the two 10-
32 x 1”
screws and #10
washers. See Figure 1 . The throttle cable bracket is attached with the rear driver
’s side bolt. The bracket in the kit works
with most throttle cables and transmission cables.
15. Tighten throttle body bolts securely.
16. Check the front fuel rail cross over tubing. This line may shift during the foregoing operations, so ensure that the line
cannot interfere against the manifold runner or the water cross-over. Adjust if necessary.
