Review on Enhanced Performance: Kelch 12.5 Inch Snowmobile Screw on Gas Fuel Cap with Gauge (54-1811) by Dan Germain

This fits perfectly and seems to work great for my 2005 Polaris Ranger 500. When I bought this 4x4, the original sensor cover was long gone. Someone replaced it with a plain black cap that didn't fit. This cap fits much better and is easier to remove when I need to add fuel. I have no idea if my tank needs a vented or non-vented cap. The one I replaced was unvented, but since it wasn't original I have no idea. I'll just watch out for when this one gets loosened. If I feel like the tank is pressurized or there is a vacuum, I need to figure out how to fix it.
