S2 and S3 Fuel Tank not direct swap
Posted: Tue Jul 31, 2018 12:59 pm
I have been trying to fit a replacement fuel tank in my track car. My car is Series 3.
I purchased an unused series 2 replacement tank and was under the impression that it was interchangeable with my S3 tank.
It turns out the tanks are different dimensions. Looks like the fuel capacity was increased for S3 and the spare wheel well was made shallower. This means to fit an S2 tank into a S3 a 40mm spacer is needed between the tank and spare wheel well. For now I will make a spacer from wood to check it fits but I plan on making a plastic or rubber spacer soon which won’t be a moisture trap once I know it will work.
If you have an S2 car I think fitting an S3 tank would be more of a problem, it might be possible with longer straps but the tank would hang down much lower which I would not recommend.
I have yet to determine if the Fuel level sender from an S3 can work in the S2 tank, will update if I can get it done.
Also Racing Beat Europe lists new S3 tanks, although I haven't tried to order one.
