Hi everybody,
I wonder if someone try to make a modification on a K75 or K100 to have the fuel pump outside of the tank. Do you have any suggestions / opinions that this will fail or not?
Thanks in advanced
-
For starters, you'd need a different pump. The one that comes on the bike is cooled and lubricated by the gasoline it's immersed in.
Next question would be where to put it.
-
Next question - WHY?

I'm reminded of the ball of flame churning out thick, acrid, black smoke I saw recently on the shoulder of the freeway that just minutes before had been a motorcycle...
-
yah I saw that too it was a Harley with a bad carbonator :hehehe :hehehe
-
Why wouldn't it work? Yes you'll need another pump, but there are plenty of cars driving arround with a similar injectionsystem so that shouldn't be a problem... Seen it done on an italian ratbike with a sporty tank, had done away with the airbox too, ran great!
-
Yeah, but what's the advantage?
-
Anything can be done that you want to do. The question is; What is the advantage or benefit? Additional fuel capacity would be minimal. Heat build up from pump is minimal as more heat enters the tank from the fuel in the return line. Still have to find a place to mount it and then run the lines.

That might have been my buddy's Ural. Carbs leaked and turned it into a big ball o flames

Russians see that as good. Warmth, even if brief.

OK, no more bashing BMW's bastard offspring. Not polite to make fun of a living fossil. And mine hardly ever catches fire, though I did mount an extinguisher in the trunk :giggles

Hi to all,
after research, it is not a very good idea because of serious disadvantages (like get fire). I just recently bought an abandoned K75S '86, and I rebuild it in a form of a cafe racer. After all the service staff that I made (oil change, spark plugs, clean of all contacts etc) I change the fuel filter also and I check is fuel pump works ok, and this idea came up to my head. After all the above discussions, I conclude that it is a bad idea.
Thanks to all for the comments
