K1200RS fuel pump replacement

I am certain this topic has been discussed earlier, so I would like to apologize in advance.

I have two questions. I own a 98 K1200RS, and I have deduced that my fuel pump has frozen up. Does anyone have the part number for a Bosch replacement ? Is there some other brand that works with this model? BMW is asking way too much for a relatively small item.

Can the pump be extracted without removing the body work? I unscrewed the filler assembly, but there is still another circular flanged gasket of sorts, that is TOO large to either shift to one side, or extracting out the fuel opening.

I don't know about the Bosch replacement part number, but the plastic and tank have to come off to pull the pump.
Check the parts fiche at www.webparts.com to see how it's assembled.

Bosch make a lot of parts for BMW slightly different so you have to pay BMW prices! There has been somebody who fitted something non-oem, but it sounds like you want more of a Plug & Play fix than to spend time looking at alternative specs. You could try a boneyard first.

To do this job properly it's best to remove the plastic and the tank so you can turn it upside down. There are issues with seals to overcome, and you might as well replace the fuel filter inside while you're at it.

Why don't you take it apart first, remove the filter (which may be clogged) and see if the pump motor will run for a few seconds (It's dry, so seconds only) without blowing a fuse?

Now I've had my pump frozen twice (or rather lockup) when I was checking the timing by rotating the crank with the ignition on and coils and injectors disconnected. I discovered you can get a pressure build up and if I release the hose connections then replace them everything is OK. The bike is 100% reliable starting and running normally, so I think this is a quirky pressure build up.

You ought to get the oem or a Clymer shop manual, working with gas at these pressures has to be done right.
