I totally agree here but sometimes the cowling space is very confined so close to the carb. I have tried to "hard" tie wrap it to the side of the carb and do not like it due to the vibrations and the reg screws grind the carb aluminum down. There is usually not space for foam up there. So then I tried "loosely" tie wrapping the reg on foam to the side if the cylinder base (opposite the exhaust). Not only does it keep the vibrations down, but the foam does not melt or even change colors. I was very surprised to see that after I took it apart after several flights. The only drawback with mine is that it is not as close as hobbsy's method and that is what Jim Cline recommends. But it works great on mine. Definitely thin CA the elbows on as hobbsy recommends. I have had nothing but troubles just snap fitting them on. They always work loose and leak fuel at the regulator's inlet (positive pressure)and air at the regulator's outlet (vacuum).

This works better than any other way. If you use a piece of yellow Tygon tubing it will have very little freedom to move yet will not be solid. Once you decide the direction you want the elbows, push them halfway on and put a tiny bit of thin CA around the fitting and then push them all the way on. They will still come off when you want them too but not by them selves.
