r u there

Make a test line and attach to the inlet side of the fuel pump, and drop into a fuel container and see if the fuel pump will work. If it does, you have a vacuum leak before the fuel pump. Without a vacuum tight suction system, the fuel pump will not suck.

already did that

And fuel pump does not pump? Is pump ever operated or pulse pump?

old type, runs off crankshaft or engine

Lever type. Sounds like pump is bad or is not being moved by the lever.??

how to repair?

Remove the pump and work the lever by hand to see if the pump is working. If not, replace the pump. If the pump does work, try to determine if the internal piece that works the pump is worn or pump lever is worn.
