4. The last lines to reroute will be from the connecter coming out of the Mass Air Flow Sensor and the
vacuum line attach to the crinkle tube connecting the main air tube to the throttle body. Remove
the hard plastic vacuum line by sliding the quick connect retainer lever on the main tube and then
simply pull the line and rubber connector to release the entire line from the stainless vacuum tube
running alongside the fuel rail.
5. Loosen the three large stainless hose clamps securing the crinkle tube and the Mass Air Flow Sensor.
Using a flat blade screw driver, work the crinkle tube and Mass Air Flow Sensor loose as these
rubber tubes tend to get stuck to the throttle body and air tube over time. Once loose, rotate the
crinkle tube so that the vacuum port is all the way down towards the passenger side. Be sure it can
still be reconnected. Now retighten the hose clamp on the crinkle tube.
6. Next, rotate the Mass Air Flow Sensor toward the driver side, so the electrical connector is all the
way down. Be sure it can still be reconnected, now go ahead and reconnect electrical connector. The
purpose of this rotation is to allow you to reroute the hard plastic line under the electric throttle
body motor. The hard plastic vacuum line just happens to be in a shape that will allow you to slip it
under this area and out to the new crinkle tube location and up to the stainless port. All you will
need to reattach the tube will be to rotate by hand both the 90 degree quick connect and rubber
tube connector, so that they will be able to be reattached. It will appear as if they were made to
attach in this new way. Now that you have successfully replaced and rerouted all three vacuum
lines you can now slip the new molded hard plastic chrome throttle body cover by tucking the front
end under the factory radiator shroud and set it down onto the throttle body. You will notice that
the new cover will fit like a glove, requiring no further attachment. Remove the blue protective liner
from the cover.
