Don't know of any free repair manuals. I can get you a link to ALLDATA or Mitchell One -- but there is a nominal subscription fee to pay.

From what I know, the fuel pump is in the fuel tank. The fuel must be removed, the tank must be lowered, and the pump removed.

This is not a reasonable backyard job, by the way. However, anyone can do anything when they set their mind to it I suppose... Good luck.
The repair manual isn't much help, essentially it says to release fuel pressure, disconnect negative battery cable, raise and support vehicle, disconnect fuel lines and electrical connections at fuel tank, remove fuel tank, remove fuel sending unit lock ring, remove sending unit from tank. to install, reverse procedure.

You will need jack stands, a good shop type jack, a special tool to release the locking connectors on the fuel lines, sockets and other tools to remove the straps that hold the tank and the clamps on the filler hoses.

Also have a second person available to help balance the tank on the jack as it is removed and when installing it. use caution around fuel, no flames, sparks or incandesant "buld type" drop lights - they can break and cause a spark ... BOOM!

You may also need strippers and crimpers, most replacement gm pumps have updated connectors that need to be spliced.

This is a job better left for a pro unless you have the tools and some experience, the locking connectors can be tricky to remove and the hose difficult to get to, good luck!
