I bought this a while back, and read the instructions then lost them :(

Does anyone else have this gauge? I know #1 is connected to the sending unit. I'm not sure about #2 and #3, one is positive and one is ground :?

thanks :)

I didn't like the thought of a hot oil line running in my car. But as log as you don't get a leak it's all good!

Is mechanical or electric more accurate? :?

i woudl think electric woudl be, because in the oil line, you get any bubble of air i would think it would throw it off. but my mechanical has never leaked or dropped in pressure for no reason ever.so all is well.

electrical is more senstive to change and if you have a horrible ground, it can jump. mechancial has the cons of running oil to your gauge.



I run an electrical one and it is fine to me.
