I just bought a 2005 Smart ForFour 1.5 CDI (70kw/95hp). Unfortunately the fuel tank is leaking but the previous owner agreed to pay for the repairs.
The problem now is that this part is no longer in production so I will have to find one second hand. On eBay there are quite a few but none of them are originally from my particular model. They do however all have the same part number, which is MR978279.
Would it be safe to assume that I can buy a tank with this number from a any diesel car on the same platform? Being either a Smart ForFor 1.5 CDI 70/90kw or a Mitsubishi Colt 1.5 DID? They all carry the same part number...
I finally got the Mitsubishi tank installed and fits perfectly. So this is a viable solution.
