I have been tinkering with a barn find '95 K75. The fuel tank was full of crud, so I had it cleaned and polished, and I ordered a new fuel pump, fuel filter, hoses, and fuel level sending unit. I am ready now to put it back together.

The tank has two "spigots" at the left side, front part of the tank. Is it correct that the rear one goes to the fuel rail, and the front one goes "somewhere in the front part of the engine".

Also, how tight should the four screws, on the underside of the tank, that hold the gauge sending unit, be? I have not been able to find any torque specs on them, and I would like to avoid leaks!
