that's the right way to do the brakes. I'd also check the back brakes, they can squeel to and it's usually to late to save the drums when they do.

Start bleeding the back passenger side brake, then back drivers, front passenger, then front drivers side. And bleed them until the fluid comming out is clear.

New fuel pumps are pretty good. I've never seen a bad one, which is good since it's so time consuming to replace them.
Replace the fuel filter at the same time, it's probably pluged which is probably why the fuel pump died.

I just replaced the fuel tank on my Blazer, and although mine is carburated it should be the same procedure for yours.

If theres gas in it syphon it out. There isn't a drain on mine and probably not on yours

I removed the plastic cover under the tank. Since I'm getting a steel mesh unit made I just cut mine off (the bolts were too rusted) Then I removed the screws from the filler neck.

Removed the front bolts from the straps, and then stick a jack loosly under the tank just to hold it up.
Now remove back bolts and lower the tank.
You'll have to guide the tank down and watch the filler tube. When the big clamp holding the filler tube is past the frame and easy to get to loosen it right off. Remove this hose along with every other hose and wire on the tank then remove it.

Putting it back on is the opposite, but if you can change all the hoses under there (except the main filler one) with longer hoses. They are just long enough to work with but too short to have a good time with.

If it was my blazer I'd probably just carefully measure the top center of the tank on the floor under the carpet and cut a 5" hole.
The tank is at-least 1" under the floor.
Then I'd do the job from the top and weld some tabs on the piece that you cut out...
bolt it back in place, place the carpet back and it's easier next time. You'd probably want to seal it up with silicone.

You wouldn't even have to drain the tank. In fact this job is safer with a full tank. (less fumes in case of sparks flying)

You'd be the only one that knows it's been done. It would take about 1 hour instead of 4 hours, and if you have to replace it again the job will take less than 1/2 an hour
