How do I remove fuel pump?

[rapdes]

I'm in the middle of replacing the fuel pump on my 1 gen explorer (94 Sport). I have the tank dropped and all the connections off, but I have no idea how to remove the sending unit/fuel pump. The entire area is all rusted to hell and I have no idea what it's supposed to look like. All I know is there is some sort of retaining ring that needs to be removed.
If someone would be so kind as to let me know what I need to do to remove the assembly that would be great and also what parts I need to order from the dealer.
If you could post some pictures or diagrahms of the area that would be even better!

thanks everyone.

A step in the right direction would to be to get a haynes manual for your truck, I know it tells me how to in mine, hold on.....I think you "use a brass punch or wood dowel to tap the fuel pump module lock ring counter clockwise until its loose." Thats for the "early models"

yup there is a brass ring that screws off that holds it to the tank..... i have assisted my coworker in replacing like 5 fuel pumps in the past month on a multitude of vehicles nad this is what basically all of them had....

Are the pumps supposed to make a high pitched "eeeee" sound because mine is really annoying when I'm not in the truck and I'm wondering if thats normal (I hope so and not at the same time!)

explorers of the earlier generations had some loud pumps.... it means they are working.... for some reason, there isnt anything wrong with them, they are just loud....

OK, so if I undertand correctly all I need from the dealer will be a new brass ring? Mine tank is so rusted in that area I can't even see a ring. All I can make out is a series of tabs all the way around the outside. Does the ring screw down into the tank a little bit? I can't see anything that a ring might screw onto either. I guess lack pictures I'll just have to start beating on that area with a brass punch until the sending unit comes out ..

Got it! After carefully chipping away and brushing crap off I figured out what its supposed to look like. Picked up the new lock ring today and will assemble tonight. Thanks to everyone who replied.

A Ford mechanic here said not to replace a fuel pump in a X unless you clean the tank first. He said that the Ford dealership that he worked for replaced a Ex's pump 3-4 times and they kept burning out. After cleaning the tank the next pump was ok!

aaarrggghhh
I finished the job. Now my fuel gauge only goes up to 3/4 full!!
I was very careful not to bend the float when installing the sending unit...and still it doesn't read correctly....aaaaarggghh!
