Curious if there's any way to positively identify a fuel pump without removing it from the fuel tank. I honestly have no idea whether I have the stocker or an upgraded pump. Been running around with the new h/c/i, and it seems to be making great power throughout the rev range, but I want to be sure I'm not holding myself back. I have a 155 lph pump that's been laying around for a couple years I should get to installing, but I was hoping I could figure out what I had first without doing too much work.
