If you haven't downloaded the service manual from here, you might want to (do a search if no one pops in with the direct link). Don't have a clue to your mechanical abilities, but this will at least let you see how "non-complex" the setup is.. I'd much rather put a new pump and filter on this car than replace the pump on my 94 silverado again!

And since we are getting a whole bunch of "best approach" opinions.. I'm just going to go sit on the sidelines at this point.
Best of luck with it my friend..
