They can get a fair bit of pressure differential so maybe the tank breather sucked in the bung till it jammed.
Maybe he was having condensate issues or whatever
It's a longshot but I have seen people do really stupid shit over the years... especially a really ugly bloke I often spot in the mirror

P.S. the factory pump should transfer at 1 & 1/2 LPM.
To work out if the pump etc is OK empty then fill the sub, note the Litres and do the following
Litres added times 1
Divide that by 2 and remember for later
Litres added divided by 10
Multiply by 5 and remember for later
If it is a Diesel set your watch forward 7 minutes unless you disconnect the battery
If it is Petrol leave watch as is but deduct 172 seconds if it is a 4.8
Turn ignition on then off 3 times quickly then once slowly (do not start engine)
Forget what you remembered and if the tank transfers 30 litres in 20 minutes give or take or 70 litres in 45 minutes give or take it is probably OK
Thanks ET, good to see there is at least one other intelligent person on the forum.
