Soak the mounting bolts with PB blaster for several days.

Siphon as much gas as possible.

Support tank with jack(s) (or ratchet straps)

Disconnect battery negative.

Loosen straps.

Slightly lower tank so you can disconnect filler tube/lines/wires.

Remove.

Replace fuel filter.

Remove lockring.

Thoroughly clean tank at car wash.

Check/inspect sending unit assembly.

Install new pump.

A good time to check voltage at the pump. With engine running, measure voltage between battery positive terminal and positive terminal on pump. Make sure reading is under 300mV. Do the same between frame and negative of pump.

If you do this job thoroughly, use a high quality turbine pump, check for proper voltage, replace filter/sock, you may never have to do this job again. You take some short cuts, life span may be limited under 2 months, or worse yet, "new one doesn't work" due to something like psi regulator/filter/ASD relay/crimped line.
Avoid replacing any part that you have not proven to be faulty through extensive testing.

Here is a little more info. Be VERY cautious of that little clear hose between pump and sending unit. If at all possible, replace. Otherwise, that $2 part can kick your ass, making you think you need to replace pump again.

You can vaguely see the clear hose that likes to get pin holes.



Something along the lines of the bosch brand pump

Or Denso with sock

New sock

You may need to locate the clear hose locally.

can't you replace the clear hose with a regular rubber fuel line.
