So I installed brand new autometer gauges, WITH the new sensors that came with them. My voltmeter works perfectly, and I THINK my water temp does as well (old one never really got very high), but all my oil pressure and fuel level do it go up to zero when I turn the key on, but when running, don't show any different readings. Any ideas? I've done continuity checks on wires from sensors to gauges, and all voltages needed are present....

if you ground the water and oil pressure sender wires they should sweep to 100%. this will test the actual gauges working. then you can always dip the water temp sending unit in boiling/hot water to see if its working properly. as far as the fuel gauge you need to make sure the old senders are the same ohm rating as the autometer fuel gauge.

did you use teflon tape on the sending units
-
That's a good idea, didn't even think of that, and yes I did, but only on the threads, no overlap onto the sending unit themselves.
-
dont use any they ground thru the threads

in the first paragraph in the link it will tell you http://www.cpperformance.com/instructions/Hardin-Gauge-Instructions.pdf (http://www.cpperformance.com/instructions/Hardin-Gauge-Instructions.pdf)
