Does anyone have step by step instructions with pics on installing an uprated fuel pressure regulator to a 2002 STI?
ie sx, fuelab or aeromotive
need this on car before mapping so if someone can help asap that would be great

off top of my head.
remove original fpr.. fit adaptor. . run fuel line from adaptor to side connector of reg.. fit blank to other side port and gauge to the smaller hole (if fuelab) if sx then gauge probably into the other side connection.
bottom of reg to tank return (ie. where the original fpr reg connected to).
connect vac line.. set the pressure.. not checked a standard 2002 sti but would assume around 3bar with vac line OFF..
Use ptfe tape or plumbers sealant paste on connections as required.

Sorry to hi-jack!
But what does the FPR actually do, can they be added to a slightly modded bugeye WRX as it looks like some nice under bonnet bling too!
