Yeah you have to remove the pump. The pump is driven by the crank sprocket. It's not that bad of a job, just take your time and have a pen magnet handy just in case you drop the pickup tube bolt. And when you put the pump back on, make sure you tighten it down before you tighten down the pickup tube bolt all the way so you don't pinch the o-ring on the tube. And make sure you get a new o-ring. You can get the LS2 chain at a dealer, I got mine at SDPC.

Here's a good guide:

I replaced the O ring, why not replace it while you have it apart. I think it was about $5 from the dealer.
I wrapped a long wire around the pick up tube bolt to be sure I didn't lose it.

Now, we need to put the front cover back on; however, it's best to not reuse the front seal that is pressed into the hole in the middle of the cover. Using a big flathead screwdriver and a hammer, hammer the seal out from the back of the cover as shown in the picture. Hammer all around the seal and work it out. This may require some pretty heavy hitting with the hammer.
Once you have removed the seal, place your new seal centered on the hole. Using a block of wood or very careful hammer placement, tap the front seal into the hole. Again, this may take some trial and error as when you hammer one side in, the other will pop up. That is where the block of wood comes in handy as you can hammer the whole seal in equally using it.

I said something backwards above. When installing the pump, start the bolts that mount the pump but do not tighten them yet. Install the pick up tube, and tighten it all the way. Then tighten the bolts that mount the pump. If you tighten the pump first you will likely damage the o-ring and have to take it all back apart.

Be sure you orient the seal properly. If you look at the seal closely you'll see that the lip is canted in one direction. That canted side goes toward the engine. That way when you push the pulley home the lip of the seal will hug the step on the pulley. If you put it in the wrong way the seal lip will be forced backwards(sort of like bending your knee in the wrong direction) and it will eventually fail. Don't beat the seal in with a hammer. Cut a 4"X4" piece out of a 2X6. Place the cover on a large flat table. Place the seal on the cover and slowly hit the piece of wood to drive the seal home.
