That's what's in my K1100LT (i.e. "Light Truck", 92) and it works just like the original. Exactly; absolute positive experience. Kit I bought came with pump.
My rubber block was completely dissolved, replacement works fine. Just had to re-use the screws, nuts and metal strip holding the rubber and plastic together.
Only noticeable difference is that the new pump doesn't show the "Bosch" name, otherwise it's pretty much an exact copy... I think I payed about $90, about 2 years ago.
