Fuel pressure did not increase with the new pump but definitely comes on stronger(gets up to that wopping 35 lbs faster). I thought pressure regulator too and that is going to lead me to change the fuel filter this morning (i already changed it in January but maybe i got a bad one). I guess the MOT valve is def on the list. What about trash or water in lines? Also, i would think that leaking lines would produce visible and smellable leaks, yes?
