Yep, originally that check valve would squeal when pressure in the section coming from the tank was enough to push through it.....that alone was enough to want it removed. But the idea of fuel being dumped into the crank was not much appreciated. Many of us did the reroute before BMW made the recommendation. I simply put an appropriate sized screw in the lower tube section after shortening it, and rerouted the other end aft....If your old tube is really brittle, you may wish to replace it with a short section of new that is closed off just to avoid the unlikely event of contamination.
