Would a 155lph holley fuel pump be a good choice for my car? would I have to upgrade anything else? I'm just looking for a step up from my fuel pump I currently have.
IMO Get the largest fuel pump available that way you won't max out the pump as you do mods. I might be wrong but I think the the pump ratings are maximum flow rates meaning that you wont use any more gas with a 255lph than a 155lph under normal conditions. But if needed, the larger pump will out flow the smaller.
