92 accord dx coupe

For some reason this car sometimes won't start, while others it's perfectly fine. It seems as if the problem only occurs if it's been sitting a couple of days. I haven't done any real testing but from the way it sounds it's not getting fuel. I know the fuel filters not the problem as it was recently replaced (after the problem started, not before). I'm thinking the fuel pump's the problem, but posted here in case I might be missing something. If it is the pump would I be ok getting one of these? The car is completely stock.

edit: link is for a 255lph walboro fuel pump

Also, if i did get the second mentioned pump would I need to buy a pressure regulator?
