I have a 1986 720 with a 2.4 napz. Everything is stock on the truck, but I noticed the water temp gauge doesn't move when I drive it. I bought an aftermarket water temp gauge at Oreilleys. The part I'm confused about is that there are 3 vacuum lines coming from the original water temp sending unit. The aftermarket gauge fits right in, but idk what to do with those 3 vacuum lines. Any suggestions?
Also, I've never installed an oil pressure gauge. In fact, the only reason I bought it is bcuz it was cheaper to buy it in a set rather than ala carte. So any help on this would be super appreciated.
Thanks in advance!
