Grahamgl Posted July 14, 2020 Report Share Posted July 14, 2020 Gentlemen, I am about to fit the Adapter fitting, item 51 in the Moss illustration, but which way up is correct? On the under dash side of it one pipe is straight and the other has a bend. When fitted should the straight pipe be at the top or the bottom? https://www.moss-europe.co.uk/shop-by-model/triumph/tr2-4a/heating-ventilation/heaters-vents-fittings/heater-system-tr4-4a-1961-67.html Thanks Graham Quote Link to post Share on other sites
RogerH Posted July 14, 2020 Report Share Posted July 14, 2020 Hi Graham, straight pipe #59 on top to valve Bent pipe #50 to steel pipe. Are you using one of the better quality USA valves. They really are good. Roger Quote Link to post Share on other sites
Grahamgl Posted July 14, 2020 Author Report Share Posted July 14, 2020 Roger, It is the under dashboard side that I am asking about, for pipes 55 and 58. Graham Quote Link to post Share on other sites
stuart Posted July 14, 2020 Report Share Posted July 14, 2020 (edited) They go like this. I know this is a 6 but same applies throughout the range TR4-6 Stuart. Edited July 14, 2020 by stuart Quote Link to post Share on other sites

John Morrison Posted July 14, 2020 Report Share Posted July 14, 2020 So the top outlet is the angled one. Wonder if there is a bit of a TR that Stuart does not have a photo of? John. Quote Link to post Share on other sites
RogerH Posted July 14, 2020 Report Share Posted July 14, 2020 It makes sense. The hot flow goes into the bottom of the matrix and the convection helps the process. Roger Quote Link to post Share on other sites
