I've a generator that is dual fuel propane/gas. Look for a disk type affair that would be the regulator between the engine and propane tank.

Prevents vapor lock by relieving built-up pressure in the supply side of the pump and sending it to the suction side of the pump. installed on many factory installations like HP/cop. The size of the relief line is so small that it doesn't affect fuel delivery volume.

Pretty much the same thing as the later vapor separator.
