first off I gotta say what a pain in the *** to remove the sc, after hours of frustration my friend and I managed to remove the SC now I have the tedious task of connecting all the vacum lines,fuel lines, coolant lines etc..!

I need help with the FMU its a cartech 2005 and I no longer will need it but need to know where the cables highlighted go

top is vacuum line - you dont need it anymore - cap it off or remove the line entirely.

bottom 2 have to be connected together when you remove the cartech, i highly recommend getting a new fuel line and running it from the fuel rail to the metal fuel pipe at the bottom of the firewall and removing those 2 hoses altogether.

so the bottom two hoses at the botttom of the cartech should only be one?
and it connects to the fuel rail?

falcongsr

yes. all the cartech does is restrict the flow of fuel through those lines so the fuel pressure goes up to force more fuel through the injectors.

Remove the cartech, connect the vac line off the FPR to the intake mani and take off the line from the FPR to the cartech and connect the other fuel return from the car back to the FPR. You're done. But if you want you can keep on the cartech because if you don't have boost, it's just an adjustable FPR.

ok also I have a hi flow fuel pump 255 (holly) should I upgrade my fuel line?
