[200q20v] how to replace fuel injectors 200q20v

[Chris Covington]

I've been looking through the Bentley on how to do this and it doesn't
really describe how.  The Bentley describes how to diagnose individual
injectors, then simply says if it fails "replace fuel injector."  It
also describes how to do a squirt test for all 5, and in doing that it
says to disconnect the fuel supply line from the fuel rail, remove fuel
return line from FPR, remove FPR and the fuel line off of the intake
manifold.  Do I need to do this just to replace the injectors?  If not,
what do I need to pull off?

thanks,
Chris
