Ran over some metal debris which pierced my petrol tank. Will be a write off if claimed through insurance, and expensive to repair at a garage. So: Is replacing the petrol tank on a 2wd Octavia 2 hatchback a straightforward DIY job? any pitfalls? (old tank is already empty via the hole!) And does anyone have any pointers on finding a second-hand tank? there are a few diesel ones on ebay but not petrol. I've put out a request on breakerlink but no joy. Is the petrol tank the same as those used in any petrol Golfs, A3s or Leons etc? as these may be more common with petrol engines than Octavias. Or are they all different, possibly due to different filler neck locations? Mine is a 2008 1.8tsi engine, though assuming all 2wd petrol engined mk2 Octavia hatchbacks have the same tank? I found this Audi A3 tank, would this fit or is the filler location different?

Besides the obvious track rod ends, where are all of the adjustment points for wheel alignment on the Octavia II? Had the alignment checked but the techs claimed they couldn't get any of it undone to adjust. They were suggesting replacing most of the parts involved at great cost. I declined. So I want to inspect myself, soak bolts in WD40 and free them up (if possible), and replace things if necessary before taking it to a different garage with less defeatist techs for an alignment!
