Very not the same... it sounds to me like you are describing the warm up
regulator, which of course is not present on the engine in question.  In
the letter you were replying to, FPR meant fuel pump relay, not fuel
pressure regulator.

Why would you do that?  The fuse is only used to set up diagnostics and 
whne adjusting timing - it's not "in" the fuel pump circuit.
