Now bust out your handy ratchet set. You will need an extension to reach the four bolts. Loosen all four bolts on the pump (you probalby will not be able to completely remove them yet.) until they are fully backed out of their holds. Now for the fun part...
PULL With everything out of the way, your pump assembly should pull right out. (Note that the long solid tube for water pickup should stay behind, so don't remove this also!) However, if you never have removed your pump before, or had it done, it will be very tight. Once you have it out, we have to begin to break down the pump assembly.
