Not too up on the senders bobble - never had an issue. They would be behind the rear boot lining though on the tank I would think. Surely though if the tank is filled up and he's getting a ot of miles before the next fill, then the tank is fine.
Interesting you tube post here.

Hi there, if I remember correctly with engine off remove petrol cap and push on the tab inside filler neck that normally gets moved over by the fuel dispenser at petrol stations. Start the car and leave to run with the tab still pushed over to allow air out, it has something to do with the float sticking as the tank in the IS200 is in 2 halfs.
