Fuel Filter Wrench for Freightliner XCR Chassis and Cummins ISL8.9L Turbo Diesel Engine Using Fleetguard FF63009 Fuel Filter. The second version, denoted by the suffix "v2", features a revised design that has been thoroughly tested. A socket fitting the filter and accommodating a 1/2" drive extension was successfully achieved, validating the wrench's effectiveness. Comparative analysis reveals noticeable improvements in the new version: the socket wall thickness has been incrementally increased to enhance durability; the depth of both the socket and the corresponding 1/2" drive opening has been marginally enhanced for better compatibility with various tools. In a deliberate design choice, the lettering has been recessed, allowing users to opt for two different filaments during printing on printers like the Flash Forge Creator Pro that support dual-head operation. Full-scale testing of the wrench revealed an unexpected issue: the 1/2" drive socket exhibited excessive tightness, necessitating the trimming of overextruded edges. Despite this, it still managed to fit properly, albeit with considerable force applied. Further investigation may be required to determine whether heat treating could strengthen the wrench and improve its ability to withstand design torque without compromising its functionality.
