Has anyone experience of fitting an Acewell 7859 to a Locost running a 1600 xflow. There are any number of speed sensors the top two listed being a bolt reed switch and a plastic reed switch. All the others cost an additional £12. Then there are 2 temp sensors which require the fitting to be 1/8 NPT. Does anyone know if the standard fitting on a 1600 xflow head is 1/8 NPT?
