To remove the filter, loosen the clamps, and remove the hose with a slight twisting motion. It might help to grip the hose lightly with a pair of pliers as you pull. Resist the temptation to pull the hose straight back, as it might pop off, or just fight you. As the filter pulls loose, be prepared for a small spray of gas; some is bound to leak, so have a rag and drain pan handy. Install the new filter, paying attention to any directional arrows, which always point in the direction of flow, then secure the clamps. Clean up any spilled fuel, and start the engine. If there are no leaks, you’re good to go.
