You're likely referring to the fuel pump inside the fuel tank of your car. Replacing that is a significantly more involved process than installing a gas station pump. It requires mechanical skill and familiarity with automotive systems.
Replacing the fuel pump in a 1995 Oldsmobile Cutlass involves these general steps:
1. Safety First: Disconnect the negative battery terminal. Gasoline is highly flammable. Work in a well-ventilated area.
2. Preparation: You'll likely need to drop the fuel tank (this usually involves removing the fuel lines and possibly the exhaust system). Consult a repair manual specific to your 1995 Oldsmobile Cutlass for precise instructions. These manuals show the exact location, access points, and specific steps.
3. Fuel Line Disconnection: Carefully disconnect the fuel lines. Be prepared for some fuel spillage; use rags to absorb it. Never work near an open flame or sparks.
4. Tank Removal: Support the tank as you lower it. It's usually heavy and contains fuel.
5. Fuel Pump Removal: Once the tank is out, you can access the fuel pump. This often involves removing a retaining ring or cover. The pump assembly is usually held in place by bolts or clips.
6. Pump Replacement: Install the new fuel pump assembly, ensuring it's properly seated and secured.
7. Tank Reinstallation: Carefully raise the tank back into its position. Reconnect the fuel lines. Double-check all connections for leaks.
8. Reconnect Battery: Reconnect the negative battery terminal.
9. Test: Start the car and check for leaks. Listen for the fuel pump to prime when you turn the ignition key on (you should hear a whirring sound).
Strongly Recommended: This is a complex procedure. Use a repair manual specific to your 1995 Oldsmobile Cutlass. If you are not comfortable working with automotive fuel systems, take it to a qualified mechanic. Working with fuel systems incorrectly can be dangerous and lead to serious injury or damage to your vehicle. A qualified mechanic will have the right tools and expertise to do the job safely and correctly.
