Liner info:
1. The first step for this installation will be to mark the location of the factory fuel rail covers edges
directly to the intake using a pencil or a silver sharpie marker. This mark will help you to set the
replacement fuel rail covers should you be installing that kit with the custom throttle plenum
cover set.
2. You have been provided with a packet of adhesive promoter. Apply this fluid to the exposed
silver fuel line between the two plastic fuel rail covers. You have been provided with a 5.5”furry
Velcro strip. Peel the release liner from this Velcro and apply it directly to the fuel rail cross
tube. Press firmly along its length to set the Velcro.
3. Remove both fuel rail covers. You will notice that your LS2 has two hard plastic vacuum lines
routed along the driver’s side fuel rail and across the throttle body. Remove these two vacuum
lines by pushing the white retainer ring in to quick release the hard plastic lines from their ports.
You have been provided with two replacement vacuum lines, one 36” line and one 21” line.
Remove the lines one at a time so as to not cross connect these lines by mistake. Starting with
the longer vacuum line, reroute the soft and flexible vacuum line so that it runs under the
engine harness sleeve between the fuel injectors and coil pack bracket. This available space will
essentially hide the vacuum line as you slip the vacuum line onto the port you exposed at the
very back of the engine. Once you have made that connection slip the other end of the vacuum
line under the throttle body and lead it up to the other exposed vacuum port and slip the
vacuum line over this port, making sure it does not kink. There will be more than adequate
space under the throttle body to allow you to reroute the two new vacuum lines in the area. The
smaller vacuum line will be able to be rerouted and connected in this same way.
