ATTENTION!
whatever I do here, I do on my own motorcycle and I take responsibility for it, my own motorcycle!
If you decide to do something along these lines and break/destroy/annihilate/exterminate your motorcycle, it's totally your own responsibility!
So, as clearly as this can be said: I AM NOT RESPONSIBLE for your damages!!!!

Replacing the fuel pressure regulator on my R1100GS!!
We had to do this too!
Copying from the service manual of the GS:

- • [RS/GS/RT] Remove side sections of fairing.
- • Unscrew fuel tank mount.

- • Remove vent pipes.
- • Separate plug for fuel pump.
- • Remove fuel tank.
- • Remove battery.
Caution:
Disconnect the negative battery terminal first, then
the positive terminal. Connect the positive battery
terminal first, then the negative terminal.
- • Motorcycles with throttle-cable divider, release Bowden-cable divider.
- • Unscrew rear battery mount.
- • Remove plug from air temperature sensor.
- • Remove air cleaner cover.
- • Detach air intake pipe and push it into the air cleaner box.

We went from this...
...to this!
In fact you need to raise the rear subframe enough so that the hard plastic lines that connect the fuel lines to the FPR and the fuel injectors are able to be removed from under the fuel filter.
So, a few pics of what needs to be done...
Spyros wondering why the heck we went to this trouble?!
From above...
This is high enough for the FPR to show its ugly self...
All the connectors on the left side must disconnect...
The left side o-ring. This may deteriorate over the years, so we would be wise to support it so that the fuel line is not destroyed due to rubbing on the harder plqastic aqirbox...
The left throttle body...
The right side TB!
Adding some soft tape hopefully helps a bit with minimizing said rubbing.
Rear ABS sensor removed, of course, along with...
...rear brake caliper!
On the right side, the plastic fuel lines are easier to manipulqate...
FPR removed from pipes, at last!
New FPR installed...
New vs Old FPR
The new part number. Actually it's the same part number, but a different make! Oh well, still very very expensive!
At last starting to get the bike back to what it was before.
I remembered to cut any and all excess zipties AND connect all disconnected connectors everywhere!
