The 2 types of fuel filters are spin-on and cartridge. The spin-on filters are the most common and are a steel canister with a paper filter inside. The cartridge filters are the older style and have plastic housings that require special tools to get them off. Keep in mind, both of these work best for certain types of vehicles and gas types. They also have their own advantages and disadvantages, so make sure you research before making your final decision.
