My parts guy had the exact Autometer gauges/cluster setup I wanted, save they're mechanical instead of electrical. I'm getting oil pressure/voltage/water temp. I have a few questions:

Basically in my opinion a water temp gauge is basically a preventative device, so hopefully if something happens I can stop it before it gets too hot. But, can water boil through that capillary tube in any way?

Basically if there are no kinks in the line I won't have problems rupturing the oil/water lines, correct?

Is the voltmeter really a volt meter (it says volts on the gauge), or do you think it's really an ammeter/ammeter that converts results to voltage?

If I have length issues, is it a bad idea to trim the line, or do I need to coil it all up somehow?

Thanks for your tips...I really appreciate it.

the temp guage doesn't send water through the line, theres a probe like thing that fits into the block/head/manifold I don't think yu can shorted the line I broke a line and had to buy a new line, oil pressure line, everyone tells me take the 1/8 nylon line that comes with the kit and throw it away, go to the hardware store and buy 1/8 in. copper tube and ferals cut it to fit, it'll give you a piece of mind and shouldn't split at a inopportune time and puke oil all over your carpet, (ask me how I know) volt meter is as it says, just pulug it in and reads voltage, ammeter goes between horn relay and measures current through Jim

Mechanical gauges are the best to install, and gives you the proper readings. The Voltmeter is low voltage and if it should short out-nothing would happen. If you used the old fashion Amp. gauge-and the wire came loose- major fire would torch everything under the dash. Be sure to use the copper line set up for the oil. They should hang the company owner who sells the plastic piece of line. When youre driving down the highway and the plastic comes apart and HOT OIL will wake you up in a hurry(burns those hairy legs- well done).If you drill several holes in the firewall-be sure to use small rubber donuts for the line to lay in-I use black silicone around the wire and it stays tight.

Taylor... Another option for the oil feed line is 3/16 SS braided brake hose. I used a 3 foot long one, with inverted flare ends. A 1/8 by 3/16 straight adpter and a 1/8 coupling at the gauge, a 1/8 by 3/16 90 degree elbow at the block. This is very flexible and will withstand high pressure. Looks clean too. Any good motorcycle shop should have these parts. Good luck.

Just a question, if I ended up using copper, would that have a chance of rattling a lot and making noise inside the car?

I've never heard a thing from my copper one. I suppose if you bent it right up against a piece of sheet metal or something it could rattle, but it's pretty stiff stuff, so just avoid that.
