Where did you place the sender for the oil pressure?

For the water temp, 1/4 up on the factory guage is roughly 165* and the center is 190*, I haven't seen it move anywhere else beyond that.

The voltmeter isn't very accurate. If it's not straight in the middle and below it, you only have about 11v and you're truck won't want to start (found that out yesterday)

I used a Glowshift sandwich adapter for the oil pressure sending unit. The Autometer sending unit is very big compared to others. I had to mount it in a different hole than the OP did in a popular post here. I also removed the plastic drip shield under the filter for easier installation. I put it back on once I was happy with the positioning if the adapter.
My Autometer water temp gauge sits at 190 for the most part. Sitting and idling, it will creep up to 210, but the dash gauge never moves past the middle.

Good to know. Post back if it starts leaking lol

My water temp on the gauge vs my SCT gauge is pretty close. Right now at cruising the SCT will be close to 190* and the analog gauge is around 176*, but it's 20* ambient right now as well. They are a lot closer in the summer

Don't jinx me! LOL
