Changing the Fuel Filter on an R1100RS - Jon Diaz

Here is the procedure to change your R1100RS fuel filter. It took me about 90 minutes

the first time....but hopefully, things will go more quickly for you!

Purchase the following before you start: a new fuel filter, a new sealing O-ring for the

fuel pump plate, and two standard BMW fuel line clamps just like the ones used on the

fuel lines by the right side throttle body (point to these on your bike if your parts jockey

doesn't understand). Let your sealing O-ring lie out for a few days before starting the

job.....I didn't and had trouble later. Let the fuel level run down, way down, so low you

don't think you can make it back to the gas station. It still won't be low enough so you

might want to siphon out from the top as well. Get as much fuel out as possible. Drain,

swirl the bike, drain some more. OK?

Remove the left and right fairing panels, the seats, and the right fuel injector cover.

Unplug the right fuel injector wire and the fuel pump harness. The fuel delivery hoses

run behind the cross-over throttle cable, and most people will have too many fingers to

keep all that stuff plugged in. Remember that there are also two screws tying the upper

fairing to the gas tank, and two little screws holding the left and right inner panels (the

ones with the rocker switches/RID) to the gas tank. Those screws must be removed.

Remove the screw holding down the back of the gas tank, and keep track of the

grommets used to fill the gap between the frame and the tank. They like to fall out....

Unplug the vent lines right next to the airbox, and loosen both fuel line clamps. The top

fuel line is holding the fuel....when you pull it, you will need to drain into a gas can until

it stops, otherwise there will be a tremendous mess. When it is done draining, remove

the other hose and lift the tank off the bike.

I laid the tank on a towel on my garage floor, right side down. Mark the orientation of

the pump plate and then loosen it; carefully pull the inside vent lines off the plate, and

gently rotate the whole assembly out. Hold the assembly with your right hand, and use

your left hand to guide the fuel level sender and fuel pump screen through the hole in

the side of the tank.

I carried the fuel pump/filter works to the bench. Anyone familiar with a K-bike will

recognize everything here except the fuel filter is held in with compression clamps. I

pried those clamps off, pulled the hoses from either end, removed the old filter and

inserted the new one, and tightened the works down with the aforementioned screw-

type clamps.

Look at the fuel level sender rod while you have the parts out. There should be an E-

ring type circlip holding the float to the rod, but some of the early bikes were missing

these and had their floats bobbing around the tank rather than registering fuel level.

I carried the assembly back to the gas tank. The O-ring must be pressed down into the
