Air fuel ratio gauges rely on a sensor that is very much like an O2 sensor used in a car's emmission system. Therefore you would have to have 'bung' drilled and welded into your cars exhaust system to mount the sensor for the air/fuel gauge. After that, run the wiring and mount the gauge like any other aftermarket gauge.

Are you sure its the gauge? A quick easy test is to ground the wire to the block. The gauge should sweep to HOT and peg. If it doesnt then the gauge cluster has to be replaced. Not real sure if you can purchase just the temp gauge in the cluster though. I think it comes as one complete package. This would require some dash removal. Not dificult but time consuming. If you want to go the cheaper route you can always mount a separate temp gauge.

Yes, you can mount a flashlight on a shotgun using various mounting systems designed for firearms. Many shotguns come with integrated mounting points or rails that allow for easy attachment of tactical lights. Additionally, aftermarket accessories such as flashlight mounts or picatinny rails can also be added to facilitate this. It's important to ensure that the mount is secure and that the flashlight does not interfere with the operation of the shotgun.
Inside. You should always place your rain gauge outdoor in a nice open space where there is nothing to hinder the rain falling directly into the gauge. Mount the gauge vertically and level, and check and empty it after every rain fall.
