Pardon me for "axing" a dumb question, but is that 54# reading with or without the engine running??? If you jump the pumps with the engine not running, that would be one thing. But, with the engine running, the fuel pressure regulator should be clamping it at around 50-52, no? 54 seems on the high side, to me.
