eBay Motors: OBX 12:1 FMU FUEL PRESSURE REGULATOR ECLIPSE TALON 350Z (item 200258157326 end time Oct-07-08 23:02:10 PDT)

hmm does look like that type of FPR, ive never seen one like that before?

what is a FMU?

 

[Jeff99GS]

Its a FMU (fuel management unit) It see's boost then tricks the FPR into sending more fuel to the injectors. The Reason it is in the back of the car is because that is where your Fuel Pressure Regulator is on the 420a.

Do NOT dissconect the FMU.
