Removing fuel pressure regulator (FPR)
How does the S4 TII FPR come off the fuel rail? Does the FPR unscrew from the nut, or does the nut unscrew from the rail? Its stuck mad tight and I don't want to break the rail cause its a long hollow aluminum tube and I lift weight. And yes, I sprayed it with WD-40 and checked the FSM. It only says remove vac line, remove fuel line, remove FPR. Doesn't show exactly where to remove it from.
