x2 just happens I'm taking mine off too.

Can anyone post how many bolts/nuts there are holding it on so I don't miss one and try to tear it off?

there should be 2 10mm bolts holding the pump to the mounting bracket. Also there is a 8mm bolt that holds the fuel return on, its on the rear of the pump and its one that I always forget.

An extension and wobble socket will get the job done. Also when taking the 4nuts off the front of the pump... For the inner lower bolt it's more easily reached by going underneath the pump and then up between the pump and block. The pump sits on a brack that has an inner and putter bolt, the bracket is located towards the back of the pump on the bottom. I found it was easier to remove the one bolt that holds the bracket onto the block and remove the pump with the bracket still on it. Also, instead of loosening all the banjo bolts on the pump, just follow the lines back till they turn to rubber hose and undo them there. Good luck getting the nut loosened on the front pump gear.
