It probably took me 24 hours total time or more, but I did it over a couple of times. All kinds of issues I had with it. Where I had the hose going the first time made the gauge want to rotate to the left. I didn't support it well enough the first time and it tore through some of the connections on the circuit board. Fixed those, then had the fixes break. Got another board from a local guy thats been very nice. Also had the gauge parts hitting the trip meter mechanicals and reading inaccurately. And yes it is harder to read where it is than a pillar pod, but I didn't want everyone that pulls up beside to see a gauge or two sitting right there. And Mark I didn't really understand what your post meant. thanks again, Micah.
