That would make sense, but it's so long since I had a bi-fuel I can't remember exactly how it works and unfortunately the manual I have doesn't cover the bi-fuel, so I can't look at a wiring diagram to see how it should operate.

When mine was faulty, it would switch over to gas briefly before the engine died of fuel starvation, so the theory seems sound.
