#14117 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 :)

#14183 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.

#22364 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.
