It is good to know that the $70USD or less pump can fix a problem that would cost far more if left to BMW....
So no issues I guess with either mechanical fit or electrical wiring harness?
In one of the other threads ... there was mention that Mahle will not seel the KL315 filter in the aftermarket that it is a captive part to BMW ...what a load of crap.... perhaps we can find a replacement unit of similar dimensions.
Your idea of external mounting is good I think - In one of the other threads which I can not find ATM a guy did that...
He managed to find a rather long slender filter and strapped to the top of one of the frame rails .... seemed to work fine!
You would also get the advantage of another ~1/4 liter of fuel capacity by moving it!
