Gas tank in position to replace fuel pump, now what?

I spent a few hours getting my gas tank in position to replace the fuel pump (rusted bolts SUCK!). I decided to stop for the night. Now my question is, how do I get the pump out of the tank? There is a round thing with tabs on it. Do I do something with these tabs? Here is a pic (not my pic, I dropped the rearend instead of cutting a hole in my car):



This is what I am looking at with the tank dropped down out of the car. What do I do from here? The more details, the better. Thanks.

You need to "unscrew" the center ring. The way that I did it was to tap the tab with a flat-head screwdriver and a hammer in the "lefty, loosey" direction untill the center ring popped out. If you look at real closely you'll see what I mean. Make sure you clean it first so that no dirt falls in to your tank when you get it open.

EDIT: Also make sure that you replace the strainer, fuel filter and the pulsator too or you'll probably have to do it all over again.

Thanks, I have a new strainer, and a filter is no prob, but what is the pulsator?

It's a little piece that goes between the fuel pump and the fuel line. When I did mine, the previous owner had just stuck a piece of hose there.

to me, it looks like a tiny little brake fluid resivoir (spell)

The new on slides into place and doesn't have any hose clamps.

EDIT: Oh yeah, I forgot. It's inside the tank. and it slides onto the fuel pump and the fuel line.

The pulsator is the short piece of hose between the pump and standpipe. The factory didn't always use clamps on these on TBI cars, but I'd install them for any type of fuel system.

Especially on a high-pressure system. The last thing you want to do after you have it all back together is take it all back out because it blew off without a clamp there.

Also, it's a good idea to use a brass punch instead of a screwdriver on that retainer ring. Brass won't cause sparks when it's smacked against steel, and sparks are bad around gas tanks.
