What up got a Vortech Fmu will my revhard kit for my LS. Does anyone know where a good place to run the vacuum line too is, or where i could get detailed instructions on complete install. Checked Vortech's website, doesn't tell muchn thanks

 

typically, the top vaccum line is T'd into the factory fuel pressure vaccum line. Then, remove the return line from the OEM fuel pressure regulator, and attach it to the bottom of the FMU, and run a line from the OEM FPR to the side port of the FMU.

 

fpr line is closer and the place I have mine.
