To find it, you'll need to:
1. Identify your engine: Is it a 4.2L inline-6 or a 2.5L inline-4? This is crucial.
2. Consult a repair manual: A repair manual specific to your 1989 Jeep Wrangler (and its engine) will show you exactly where the fuel filter is located. This is the most reliable method. You can find these manuals online (eBay, Amazon) or at auto parts stores.
3. Look near the fuel tank: It's *often* near the fuel tank, but not always directly on it. Look along the frame rails near the tank. It might be in a metal bracket or strapped to a component nearby.
Without knowing your engine, I cannot give you a precise location. Incorrectly locating and working on the fuel system can be dangerous due to the flammability of fuel. Always use caution and consult a repair manual before attempting any fuel system work.
