I think that I may have made a mistake here. Sold my old '85 740 and took the locking petrol cap off to use on my '92 940 2.3i. Now when I drive with the windows or sunroof open I get a strong smell of petrol. The cap seems to fit ok but it is vented, is this likely to be the problem and if so, where can I buy a new locking cap in the UK??
Thanks Taff.........
