The car has never been in a collision and I find it needing a new fuel tank highly unusual, can you offer any advice or does this happen

Can you tell me if they smoked tested the tank? Are they able to actually see the leak? Any signs of rodents? Thanks!

OK,you are in Australia and not sure of the emission laws there because in the US,it is required the tank is sealed. It is probably the same in Australia because they use the vapors to make adjustments in the fuel trim. It is introduced into the engine as sen needed by the computer via a small frequency valve. They vibrate but they are just opening and closing real fast. OK, so if they are asking for this much money, you need to see the leak. There are some very aggressive sealants that could be found by a Google search that could attempt to patch the leak. Depends on where it is. Can you elaborate more on what transpired?

You just bought the car and it had this problem?

Maybe an accessory was installed in the trunk and damaged the tank with a renegade screw?

When do you smell the fuel smell? During fill up?

Howlong has this been going on?

It is currently 8 pm here

I will await your reply. If too late,I won't be able to reply

Also the fuel tank is plastic. Porsche has not used a metal fuel tank since the 1989 911. I do not understand how the tank could have corroded when it is made of plastic.
