Ok, in this case theres a mechanical fuel pump on the pump. So we need to unhook the fuel lines from the pump going to the filter (5/8" box wrench) and the fuel line supply to the pump (flat screwdriver). Thia is were you need the rags!!! You will also need to unhook the two water lines off the back of the pump. Make note as where each one goes to. You mix them up and you WILL ruin a brand new inpeller on startup!!! And when you have done all that you will need the 1/2" socket and drive to loosen the 4 bolts that hold the pump to the bracket. When you look at your pump assembly you will see that there is one bolt that has a nut on the back side......leave that one on as its not affecting removal of the pump.
