I'm pretty sure the fuel pump in my car is starting to go so I was looking for a replacement. I notice some walbro 255 lph pumps for like 100 bucks. Is that a good deal. Also my car isn't that modded, but i was thinking about a big pump for the future buildup of the car. Anyways how hard is it to replace the pump? What lph does the stock pump put out? and would I need a fuel pressure regulator to help me out? Thanks guys
