I have the same problem as Wayne on the resurrection I am trying to perform on an NS250 that sat many years; fuel pump.
Looking at the respective positions of the components and applying the principles of gravity, would it not be reasonable to assume the fuel pump could be bypassed/eliminated completely?
Currently the goal is to make it run before staring in on any cosmetics (it needs bodywork repairs and paint). If it runs fine and doesn't need crank seals or something 'engine out and apart' major, I'll go ahead with making it pretty. Otherwise it goes down the road.
Other than a few details, the bike is essentially unaltered or modified with about 19K km on the dial:
