My 924s had been smelling badly of petrol (or rather gas over the pond!) and on looking underneath the hardline pipes from the boot floor down to the suspension tube were looking very corroded with signs of petrol on the floorpan. My course of action was to try to splice on new hardline sections replacing the corroded bits (forward of the rear suspension the lines looked fine). I dropped the transmission and fuel tank to gain better access and as the tank looked pretty corroded I sent it off to be pressure tested. The result is the tank has gone at the seam and the company looking at it said whilst they could offer a "Re-nu" repair at some £370 + but probably I was best off getting a new tank. As I understand these tanks are not cheap (some £1500?!) I am considering a petrol tank sealer such as POR15 - the type you swill around inside the tank which is meant to seal the tank from the inside.
Has anyone experience of using this product and if it actually works?
