Dual Fuel Tanks Jun 3, 2019 10:18:06 GMT

I have just acquired a Mevabusa with dual fuel tanks - I had some fuel supply issues and discovered one tank was dry (sucking air) despite the fact the other was half full. By blocking off the empty tank all is good, but I would like to get it working properly with both tanks - I am struggling to see how it works. Both tank outlets feed to the lift pump which feeds the surge vessel which feeds the secondary high pressure pump. Excess high pressure feeds via pressure regulator back to surge vessel , and surge vessel overflows back to both tanks via a t connector. There can be no low level connection between the tanks due to the central tunnel. So if the fuel return t piece prefers one tank, then it will get most of the returned fuel , starving the other tank. What am I missing? This an original factory built busa, so I assume worked in the first place?
The clutch bite point is very brutal - i wondered if this may be due to the master cylinder (not sure what it is or where its from) being too big for the slave. The slave in the Hayabusa engine appears to be internal with no apparent adjustment (I am awaiting my Hayabusa Haynes manual).
There is a simple mechanical linkage for the sequential shift . 50-% of the time neutral is easy to find- but the other 50% can be a bugger. I end up having to pull the car forward in gear and try again. As the electric reverse can only be engaged in neutral, and i live down narrow lanes this could be very embarrassing when it takes me 10 minutes to find neutral.
Other than that loving the car - but any help on the above would be gratefully received.
