cheapest place to buy?
Online? I can get dealer discount to around $720. Am I going to beat that online?

I checked online and they are all around 730 dollars which included the fuel pump WITH the installation kit.

Try calling Shokan (1 800 all audi) for a used part, used fuel pumps may be as low as 200 dollars I beleive

good luck!

You can get just the pump for $200 from England. Very reputable seller and fast shipping.

Is it an easy enough process to swap the other parts? Looks like a deal to me.

Never heard anyone say it's easy:

Most of the work is getting the pump assembly out... and especially getting it back in and seated properly. Swapping out the pump from the assembly once it is out of the tank is relatively easy.

I posted a step by step about 10 months ago. I'm not so good at searching the forums... otherwise I'd send you the link.. I'll see if I can find it.

Getting the assembly back in the tank, and getting it to seat properly is a bit of a pain. I'm still not sure what the proper method is -- for a while mine would not suck up the fuel from the bottom half of the tank... Then a few months later I was in the mood to troubleshoot it, but discovered that the problem had fixed itself. I'm still not sure why... Somehow it was not seated, or possibly I had air in the in-tank lines and passive pumps. The pump assembly mates to a lower half that stays in the tank...and it is this step that seems to be difficult to line up.

The step by step that I had posted was to remove the pump assembly (which is not so obvious if you don't have instructions). Everything needs to go back in reverse, of course... but I don't know the trick to getting it right the first time.

Here you go... my step by step for removing the FP assembly...

First remove the black metal cover in the trunk on the right side of the tank.

1. remove the small white cap -- this covers and contains the tube for the fuel level. I took a piece of 1/4" steel (1.25 x 12 inches long), drilled two holes and bolted in two 10mm bolts to create a tool that will fit into the two round holes in the top of this cap. Press the flexible tabs on the sides of the cap and turn it clockwise until the two small arrows line up. then pry the cap out with a screwdriver. Then reach in with pliers and grip the top of the tube inside and pull it out until you can grab it. It's about 10 inches long, and will slide right out... you'll need to unplug the wiring while pulling it out.

2. Remove the bolt on top that goes thru the entire assembly and screws into (something) at the bottom of the tank.

3. Next detach the fuel lines if you have not already done so, and unscrew the large black ring. To do this, I took another piece of steel I had hanging around, and welded 1/8" x 1" x 2" steel pieces to it...and bent them to fit the grooves in the side of the ring. And used it to loosen the ring the first turn or two. I'm sure there are many other methods...but somehow you have to get a grip on this ring to unscrew it -- or obtain VAG-Tool 3778984-A12-Fuel-Ring-Unscrew-Tool-21B. ;-) It threads off counterclockwise just like a standard thread.

4. Now you just pull up on it, then tilt it and rotate the entire assembly one way or the other while lifting it out.

I wrestled with mine for a while before realizing that the fuel level float tube is the first thing that must come out. And at that point, I had already done everything in step 2 and 3, so I had to find a way to grip the assembly while turning the white cap.

Once the assembly is out, it's relatively obvious how to disassemble it the rest of the way, if you want to take out just the 4" pump. Mine seems to have some foreign matter in it causing it to jam. I can make it come on and pump, but then it jams again.
