Why has my LPG powered car started to drink petrol when running?
Agree with first one, — it can’t get there any other way! Perhaps there is something caught in valve that you might be able to flush out if switching rapidly from gas to lpg while rolling under compression from a rasonable highway speed, — this will keep it from backfiring much, and not “jerking” engin earound in mounts much! If you have a “hose” going to cutoff valve on gas, – try putting a pair of lockgrips on hose using minimum pressure, – (and cardboard between jaws to prevent damage to hose), — if the leak now stops, you know it isn’t “cold start” injection valve (which some engines have, – to put extra gas into plenum for “prime” to start engine)! As this could be a problem too!
