Oil pressure, obviously.What exactly do you want to know?
Just about any oil pressure gauge will work, you will need a 1/8" BSPT adapter unless you get a gauge with it, most gauges come with NPT adapters.
Steve,not having gauges on my b7100 is my biggest hang up for the tractor. this is how I added some to it. oil pressure, volt meter and temp gauge. I bought the triple set from auto zone for 29.99 1.5 inch faces on the gauges and a brass tee so I could also keep the oil pressure idiot light.
sorry the pics are upside down computer refused to work with me on that
I like the radiator overflow tank Cat! That makes more sense to me than just a whistle. My whistle is messed up and I really cant seem to stomach the $90 replacement cost. I might just have to steal your idea.
How has the overflow tank worked out? Is it a worthy mod?While you're doing you oil gauge modification, here's another. I got the tank at the auto salvage yard. Just walking around until I found a small one I thought I could make work. Virtually no cost, and it eliminates the whistle you hope works and you hear it!
