see photo attached, 2 outlets, the one on the left been larger thread size, can someone please tell me which outlet is for the front and which for the rear ?

This is the info I have on the cylinder, thanks.

Hi Jon

I've just checked on my 90 Defender.

Front larger one to the fronts - smaller rear one to rears.

I presume yours will be the same.
