i need exact answers on this, and how hard was it to do this?

Just buy a digital one from dynotune. There is a sender unit that replaces thae gauge back near where the bottle mounts. From there, you just run the electrical wiring up to the pillar and you're done. Not sure how the gauges from the other companies work.

 

If you use a mechanical gauge you have to run a stainless line to the gauge from the bottle. Just tuck it under the carpet if you want!
