Dont know about your 06', but the 02'-04' bottle pumps are cheap. I bought one from my local dealer for like $28 all said and done. It's a bear to install...but very affordable. The resivoir on the other hand was pricy. I originally thought I had a hole in mine and ended up buying one. It cost around $140 for a stupid plastic tank!!

I returned it after finding that my problem was the a hole in the pump.
My guess is that the pump, if anything, is the same on all KJs. After the bumper change...or slight change in front ends on the newer KJs from the old...the bottles themselves may have changed shape. But I would think the pumps are the same.
