Where is the fuel filter on my Acura cl 3.0? It is a 1997.

Check below the driver's floor at the back of the engine compartment from below. If you verify you have this type, it will be as big as a short wide coffee mug. It will have tubing flare nut fittings. The honda specialist or the dealer should be consulted because these fittings can leak unexpectedly or be the cause of line replacement needed. You must give them a call to help decide what's what on yours, and decide what to do. They are not normally replaced till 60K because of this design, in my experience.
