The Club Car Carryall and XRT Fuel Filter is the very first line of defense in keeping your engine trash-free. You should always try and use ethanol-free gas where possible. This typically has less debris in it to begin with, and ethanol does nothing but harms your system. The fuel companies use it to boost octane ratings these days instead of its intended uses, and it is hell on your fuel lines and components like the carb and pump.The golf cart filter is an inline strainer of all harmful bits that can clog and gum up the fuel system and engine. The older it gets, the fuller it becomes and reduces its effectiveness. We recommend you look at changing this unit two to four times a year depending on use. Since this is not really a golf cart and more of a utility or work cart, the service will be more strenuous, and you may need to replace it more often.
