Just got my turbo kit and putting it on right now. But I forgot how the FMU hook up . Is it the one with the hose go to the regulator and the other one go to the fuel return line? or is it the other way? TIA

 

SpeedracerS4,

The SIDE fitting of the fmu goes to the factory regulator and the BOTTOM fitting of the fmu goes to the return line to the tank. The top vacuum fitting should be tee'd into the vacuum line that is on the factory fuel pressure reg. Hope this helps...
