Default Fuel pressure issues

I pulled my car out of storage lastnight and noticed that my fuel pressure guage is only reading 49psi at idle and when driving around. I've only got 26k miles on the car. Is it possible the fuel pump is crapping out on me? I believe everything was fine before storage. I'm going to put a mechanical gauge on the rail and read it from there to double check but if it's still reading 49psi then the pump is crapping out, right? Thanks for any help. I'll just budget this week for the new fuel pump.

Change the fuel filter before you do anything.

Changed the fuel filter lastnight. Still reading 49-50psi. I thought the norm was about 55psi? Should I be worried or is the pump going out? Again the car's only got 26k miles on it. I'll be sea foaming the engine shortly. So I need to know what my next step should be. Also does anyone know where I can get the write up on how to do the racetronic install? Thanks.

the racetronix PnP install is just that. there really aren't any directions, and racetronix does send you directions with your purchase

you sure your gauge is reading correctly?.. gauges DO GO BAD. i had 2 autometers go bad..the sending units crapped out

my car constantly ran 56-58 at idle and driving around and 60 WOT.
