Agree. But for a "fuel" fire he's trailing a lot of smoke for a long time if the valve was closed. Oil/Hyd fire something different. Maybe an oil leak ingested by engine causing performance issues then a fire at the end? Have even seen oil leaks on the xsmn deck dump excessive oil down the intake tunnel.
