Well, my 164 leaked with the original hose, it leaked when I fitted 5/16" 
hose, and it still leaks now that I bought and installed the expensive BMW 
hose. It leaked when I used radiator-type screw clamps and it leakes when I 
use "fuel hose" clamps. It leaks when I use one clamp and it leaks when I use 
two. Must be my technique. The only thing that stops it from leaking is 
frequent checks and clamp tightening. 
I agree that having fuel sparying around the engine compartment is not the 
best thing, but, at least in the absence of an open flame, it seems to be 
more of an annoyance than it is a hazard. And it can't help my gas mileage 
much.
