Gauges sizing
 

Well after i recieved my oil pressure and water temp gauges i soon found out that niether the oil pressure sender nor the water temp sender swap out for the same size. I found by searching i need a 1/8 NPT TO 1/8 BSPT for the oil pressure but im unsure about the water temp sender. What size is the stock one? What size is the prosport one? The prosport sender seems much smaller than the stock but i dont know what size i need to buy, i need this stuff asap so please help out!
Thanks.
