there are lots of documented cases of the fuel command center failing. mine was one of them. I did try it. ended going with a tank mounted pump. don't know why it failed maybe not enough fuel flow? needs a real return back to the tank to circulate fuel so it won't over heat.

if you are going to try it. make sure you attach the vent line to a fuel return line back to the tank. plenty have tried not to, only to have fuel shooting out of it. its almost as if the float fails.
