| Leaking tank mystery
My G has a leaky tank, assumingly due to rust. The leak was so bad it would drip, not just sweat a little. I once measured the biggest drip point to shed about 1 litre of diesel over 24 hours. I would leave small puddles everywhwere and my driveway smells like a gas station. I found another tank in very good shape and am in the process of cleaning and rust-proofing it.
A few days ago my wife congratuleted me for finally swapping out the old one, only I hadn't done it... The leak has mysteriously stopped.
I have not disassembled the ex-leaky tank yet so I do not know where the leak came from. Is it possible that a blocked vent line or something like that could have caused blowback or anything? Could a hose have gone dry during the 1,5 years of hibernation and now have swelled up to fit?
I had to chase spiders from the turbo so I'm not convinced that my vent lines are pest-free and unclogged. I'm puzzled, because it has been leaking badly for 5 months, and now it's not leaking at all. I guess I should pull the tank anyways but I'd thought I'd check the vents first |

If you are going to the trouble of swapping tanks I can recommend POR15 tank repair http://www.frost.co.uk/item_Detail.asp?productID=8223&frostProductN...
Its about the consistency of double cream, you slosh it around the tank and it coats the interior.
I did mine about 3yrs ago and it’s been perfect.

Have you checked the rubber hoses under the little square plate in the trunk/back area under the mat? I replaced all mine by snaking them through to where they were connected to the hard lines. Without removing the tank.
This was where mine was leaking from.
