Need to know what part number I am looking for a water pressure gauge for a VZ225TLRD. I have a Champion 21sx and would like to take out the analog speedo gauge and replace it with a water pressure gauge (it does not already have one). Any suggestions on part number for the water pressure gauge that would fit in the hole. It is not the small gauge it would have to be the larger gauges like the tach and speedo to fit in the hole.

Also, what else would I need to hook up this gauge to my yammy, such as wires, etc?
