It is time to change the fuel pressure regulator (FPR) in my 2001 LB7 Duramax GMC Sierra 3500. My removal procedure is slightly unorthodox compared to other processes you may have seen. I only remove the cold air intake and turbo horn, bend one fuel line out of the way then use a select set of small tools you can pick up at any hardware or auto store to remove and install the FPR unit. It's not rocket science, but it is the quickest route I know of.
