I want to replace my Truma gas regulator with an automatic changeover including regulator. It looks very straightforward apart from the issue of knowing which connections I need: 10mm or 8mm connections. It's not easy to measure the diameter of the gas pipe when there's only 2mm difference! If I enter Truma EN61-DS for the existing regulator, it still give me a choice of 8mm or 10mm. Any clues? This is the existing regulator....
