Hello all. I am glad to be a part of this forum. I have just purchased a 2007 Rhino. I want to modify it already by installing a tach and oil pressure, coolant temp and ammeter gauges. I notice that the kits I look at have US sized fittings. For example the oil pressure sender is 1/8" NPT and the coolant temp sender is 5/8" NPT. So, my question is if the Yamaha engine has those thread sizes. Or are they metric? Thanks for your help.
