Oh yeah, what a pain in the ***. I'd rather sever my **** than deal with ground-offset bullshit, incredulity. AEM from TSE it is.

I also don't feel like grounding them directly to the battery, so...

I'm going to sell them and get to sourcing new senders for my 20 year old HKS gauges and i'll just use those.

What you need to do is to ground the gauge in the same place as the sender. If it's a 1-wire sender then you ground the gauge to the block.

Yep.

Other than the big drawback of having to run large lines into the cabin of the car, mechanical gauges are awesome.

Not really, the water line is already going through the driver side so just gotta intercept it.

Mechanical temp gauges use thermocouples (like a heat pipe). Not to be confused with thermocouples (2 dissimilar metals joined that make a varying voltage offset proportional to temperature).

Agreed. No wiring, no shorts, it will tell you the temperature without having to turn the key on , no sending unit to fail. Just make sure you don't put too sharp of bends in it, it will break the core. The only electric gauge I have is my wideband. Better watch out for those mechanical lines though, they might EXPLODE

And mechanical gauges can be had for cheap anywhere from O'Riellys, Autozone, PepBoys, Summit and they are usually going to be very accurate.

Yeah I think I'm going to be switching to all mechanical gauges (besides oil pressure). I used to be all gungho electrical but my electrical boost gauge is starting to not work all the time and **** and its pissing me off. The mechanical VDO in the subie is stone reliable and moves faster than the electric one.

Mechanical temp gauges generally use a bourdon tube, which is large and kink-sensitive (the tube has to be routed carefully with a min bend radius and if you split the tube you throw the whole shebang away and buy a new one). The bulb at the business end is also large/bulky. They're accurate but sort of a pain in the ***.

I was originally going to say mechanical but I figured Mr. Baller would cry about it not being shiny enough. Ballers like shiny things.
