Oil Pressure & Temp Install

[Jlee]

Hey guys, so I have a Megan oil pressure gauge and a Megan oil temperature gauge that I wanna install on my redtop SR. Yes, yes, I know they may not be the most accurate gauges but I bought them when I first got my car and figure I'd might as well run em now until I have money to get some decent gauges. I didn't want to drill into the oil pan for the oil temp sensor so I went out and bought a 1/8 female pipe tee. and a 1/8 hex nipple.



The instructions that came with the gauges is specifies:

"Do not use teflon thread sealer tape on the sending unit. This will cause a ground problem and the gauge will read inaccurately. It is highly advisable to ground the gauge at the engine close to the oil sender."

Now... my question is, to those of you who have installed oil pressure/temp gauges, whether it be Megan or any other brand...

1. did the instruction included specify the same?
2. And if so or if not, is there any kind of thread sealant that I could use that won't cause a grounding problem?
3. did you ground close to the sender? if not where?

I don't want any leaks. Thanks in advance.
