I had a look at the back of the diff on my Roadster and was surprised just how close it is to the front of the tank.

I was pleased to see that it has no brackets or anything on it that might impact the tank, but the sheet steel tank is unimpressive and past its sell by date.

It is time the MMC paid to have a modern moulded plastic tank made. A plastic tank is far tougher and less likely to split in a rear end impact, can be made to fit the shape of the back of the car much better and cannot rust.

To be honest I thought steel tans were no longer allowed.
