I wish I took some pics. So, the top end of the pump is attached to the lower via 2 tabs.
Push the tabs in and the top end slides away.
There are two wire connectors at the top (both have plastic pins a green one and a red one that need to be pulled) and those pop out.
There are two hoses that go from the actual pump that's in the canister to the top. Cut whose out because any kit you buy has relacement ones (or they should)
At that point, there should be one more wire connenctor that located at the pump and if I remember right, it has a gray pin. Pull the pin and release the connector and the housing should be free from the canister.
Finally, to free the pump, just wiggle off the filter and it should be fully disassembled.
1 note, I'm doing this off of memory so some specifics may be different but it's essentially all there. I'm actually so "pumped" (pardon the pun) about this that I'm actually buying a couple cars from tw ofriends who ironically had their fuel pumps go out. The shops quoted them $800 and $1000 for their cars to be repaired and they're just giving up. I'm buying these for a $100 each and redoing the pumps via the kits and maybe just flip the cars for some quick cash.
BTW, I did offer to help them, they both declined so I'm doing them a favor and saving the cars from the green mile.
