URD Vacuum Line Assembly w/Restrictor T URD 5VZ Fuel Upgrade Kits

This is the same vacuum line assembly that we ship in our fuel kits including the 7th injector kit for the 5VZ 3.4L applications.

This restrictor T assembly is used in our fuel kit and 7th injector kit for the TRD/Magnuson supercharger using the older 3 lobe MP-62 rotor assembly.  This prevents impeller noise/pulses from traveling through the vacuum line to the Performance Calibration Unit and makes the MAP sensor BUZZ.

This is not needed for the newer Magnuson supercharger using the TVS-1320 rotor pack.  Just a simple vacuum line assembly will work fine.
