Tip: if using the cable bypass, ensure a 'car' fuse is used as this can be used as a 'switch'
The fuel pump issue on the 800 is different-
Reading all this makes me glad I kept my old thumper (aka Dakar)- an Oldie but a Goodie!

Cheers. So is it worth carrying a fuel pump bypass cable? Is 'controller' failure that common on the F800GS?

While I wouldn't say that it's very common, I know of more than one traveler that had a failure of the FPC. The cable or even a second FPC are small and light enough that I would include them in a spares kit.

Good to know, thanks. The fuel pump controller bypass cable is a bit cheaper than the actual fuel pump controller unit as I recall so I think I'll go with that. I wonder how failure of fuel pump unit v fuel pump controller compares? Seems the controller is more often than not the culprit. I think it's definitely worth taking a fuel pump controller bypass cable (or fuel pump controller) and maybe even a fuel pump unit itself if one can be found cheaply enough? Time to start looking...

Fuel pump issue
a bit out of date but just back from 17 days in southern africa on a F800 GS. We had fuel pump issues, solved by replacing the OEM with an identical and much cheaper one from a Toyota Corolla. The issue seems to be the thermostat in the BMW one cuts out at consistently high temps. The Corolla does not have a thermostat. Have seen the ads for the bypass kit but for £30 the Toyota one was a dream. BMW dealers seem to be unaware of this issue which has been flagged on various sites.

I had problems on my solo Mongolia & Siberia trip this year, lost power for a second on multiple occasions. Took it to BMW in Germany who put it on the diagnostic and, just like my dealer, could not find a fault. It did it mostly in Europe on my way east, when it was hot weather. It wasn't a show stopper, I gritted my teeth and went for it, but it is frustrating and a little disconcerting when your in the middle of nowhere. I'm convinced its a fuel pump/controller issue. I want to swap it out but who knows if your putting in another dodgy BMW pump, and they're so expensive new. And of course used ones are rare and I question the reliability of these too.
Will defo look into the Toyota Corolla fuel pump replacement. Do you have any more info on the model, year, part number and price of the Toyota Corolla fuel pump?
Cheers

Overheated fuel = blocked fuel filter on EFI
A 'common problem' on K75/100 and K1100s has been the fuel filter being blocked (usually water and dirt).
It presents it self as bad running, when the fuel level is low and high temperatures (both ambient and engine). If you stop and wait for it to cool the problem goes away until the fuel heats up again. Or you refill the tank (fresh fuel is cooler, and more fuel gives a larger surface area to get rid of the heat). Feel the fuel temperature if you can - or look at the fuel pump in the tank - people report seeing the fuel boil  around the pump.
It should be less of a problem with CAN buss controlled fuel pumps as they won't be running flat out all the time (some 60 watts  ) but if you are running hard you could end up with the same kind of problem.
Message - check the filter before spending big on a new pump. If there is 'no filter' look for wire gauze on the pump itself.
============================
If stuck with a failed fuel pump - go to a car wreckers and get a EFI fuel pump ... while it may not 'fit' in exactly the same way .. it should work ... if not try a different car for its pump ... you should be able to find one good enough to continue.

Interesting, it did always seem to be when the fuel was low. I'll look into this possibility too.
