Where is the gas filter located on 1987 Toyota corolla?

The 1987 Toyota Corolla's fuel filter is in-line within the fuel line, usually somewhere near the fuel pump. It's not easily accessible and often requires some work to replace. Precise location varies slightly depending on engine type and model specifics (e.g., sedan, liftback). You'll likely find it somewhere near the fuel tank, possibly under the car, and possibly close to the engine compartment.

To find it, you'll need a repair manual specific to your 1987 Corolla's engine type. A repair manual will have diagrams showing its exact location. Searching online for a "1987 Toyota Corolla [your engine code] fuel filter location" might also yield helpful results with images. Note that the engine code is usually found on a plate in the engine bay.

Without knowing the specific engine code, it's impossible to give a more precise location. Be aware that working on fuel lines requires care to avoid fire hazards.
