I did see one sell for £1500 on fleabay but I can't believe someone would actually pay that for one..?!

I know the suggestion for a 2wd is to use a 4x4 one and get a different hose

but how does it work for a 3dr as the 3dr uses the same tank as the 2wd but the 2wd has the sensor thing blocked off?
