8. Remove the last vacuum line from the valve at the front of the passenger side engine head completely and replace this line
as well routing it along the wire harness that stenches across to the wheel well bracket. You will need a small plastic release
tool for this line. This can be found at any auto parts store costing less than a dollar.
9. Next remove the plastic engine cover retainer by removing the single 10mm bolt securing the one end. Once removed lift
the bracket off the fuel line and then replace the bolt. Save this bracket for restoration.
10. The next step will be to reposition the engine fuel line. Remove the 10mm bolt holding the single line clamp to the engine.
Once this is released snip the end of this bracket so that the hole will become a notch using a common tin snip. Rotate the
entire line so that it will be rerouted behind the engine. This line will rotate easily at both connection points allowing you to
relocate the line bracket at the rear passenger side plenum bolt location. Loosen this bolt and then slide the bracket you
snipped earlier and then secure. Because the metal line is very stiff you will need to manipulate the line a little to get the
right placement. Tip the passenger side end so the line will be able to be routed in back of the heat shield you routed the
heater hosed earlier and then zip tie its position to the brake line there so that it is nice and secure.
11. The last thing you will need to do is tuck the three main wire harnesses so that they will no longer be stung over the top of
the coil packs. To do this removes all the fasteners of the harness. Detach each of the spark plug wires on the passenger
side and route the lower harness under the coil pack bracket. You will notice a hole in this bracket. Use this hole to secure
the harness using a zip tie. Reinstall the spark plug wires. The two remaining wire harnesses can be tucked just below the
fuel injectors by unplugging each of the injectors and tucking the two harnesses below the injectors and then simply
reinstall the injector connectors to finish the engine line tucking procedure.
12. Replace the factory air tube assembly.
1. With the engine wire tuck procedures completed the first step will be to install the Four 1/4 20 clip nuts provided in
your kit directly to the newly exposed tabs protruding from each of the two fuel rails. Set the clips in place so that the
threaded sleeve of the clip nut faces inward toward the plenum.
2. You have been provided with four flat headed bolts and four tight stainless washers. Place each of the bolts through a
washer. Set the new shroud over the fuel rails and align the holes. This may require you to slide the clip nuts around a
little until you get correct alignment. It is important to know that the new shroud has been designed to not touch the
plenum leaving a varying space all around the part. Should you elect to paint the factory plenum cover; this space will
serve you well in not damaging the plenum while allowing lighting to shine up through if you chose to install the lighted
version of this new shroud. Although it should not be necessary to adjust the shape or angle of the new plenums sides,
we have supplied some spacers to allow you to set the new shroud to the fuel rails without warping and or changing this
angle. Simply set the new shroud in place to determine if spacers are needed, if any at all.
3. Once you have achieved a nice alignment and everything looks to be nice and even simply install the bolts.
TECH INFO; the tight stainless washers need only be used if you are also installing the ACC custom fuel rail covers. This washer is
provided to create a space for the fuel rail cover to slide onto. If you are not installing these parts at this time do not use the washers
and simply snug the bolts after removing the protective liner.
4. If your new shroud is an illuminated version you will been provided with a single red and black fused wire harness.
Prior to installing the new shroud simply route this harness up to the engine plenum and secure it with the zip ties
provided. The electrical connection should be routed toward the heavy red battery jump post. This will require you to
obtain a switch and additional electrical connectors that will allow you to place the switch at your desired location.
