Look on auto parts websites to find the price for the fuel filter compatible to your vehicle. As of 2015, these prices range between about $10 and $100, including shipping and applicable sales taxes. The reasons for the price range include brand quality, fuel type and engine type.
Northern Tool and Equipment carries a number of different fuel filters, including the Goldenrod Bio-FLO biodiesel fuel filter. The Features + Benefits section on each product page provides a diagram of the filter, pointing out distinguishing features of that filter. In the case of the Bio-FLO filter, the nickel-plated top cap is marketed for durability as are the stainless steel components on the internal element.
Look at your vehicle's owner's manual often indicates the compatible fuel filter, and auto parts stores offer online and/or in-store resources to help the consumer find out which model he needs in different brands. Run a shopping search for the compatible fuel filters to gain up-to-date pricing for the fuel filter that you need.
Choosing the cheapest fuel filters does not always provide the best value for your engine because it can hamper performance. However, some reasonably priced brands provide superior performance, so look at third-party reviews on such websites as Amazon.com to read other consumers' perspectives on various fuel filter brands before making a final decision.
