Hello we have a Pioneer D50 truck mounted forklift. It has a fuel line leak if you stand in front of it and look under seat area on top right of the motor above the motor mount there is a black rubber fuel line in a j shape that's leaking. We can't find any fuel diagrams or service manuals. Before tearing machine down we would like to know where it goes? It can't be seen by lifting door in rear of machine either.
