Hey all. I found some info on this topic, all pretty vague. So I work for Factory Five Racing where the kit cars we build use foxbody's as donor cars most of the time. I get a lot of cool cheap and sometimes free parts from the big wigs around there. Recently I got my hands on a literally brand new Walbro 255 lph fuel pump that they were just gonna throw away. My 87 5.0 HO (still with speed density) is basically stock (underdrive pulleys, GT40 upper/lower intake, and new plugs, 9mm wires and an MSD cap and rotor.) so my question is, would I be able to use this pump without any issues? Like will it be pumping more fuel than my engine needs or will the ECU regulate that on it's own? Confused as to how this works. I know the pump is good for serious power I just don't want to put it in a basically stock 5.0 and have it cause problems with my fuel air ratio or anything like that. Thanks in advance.
