Common Problems & Solutions:
* Incorrect Alignment: The tank needs to be perfectly aligned with the straps and mounting points. Even a slight misalignment will prevent it from seating correctly.
* Solution: Carefully examine the tank and the mounting points. Use a flashlight and possibly a helper to guide the tank into position. Gently wiggle it and try different angles until you feel it start to seat. You might need to adjust the straps slightly as you go.
* Straps are Bent or Damaged: The fuel tank straps can be bent or broken, preventing proper seating.
* Solution: Inspect the straps thoroughly. If they're bent, carefully straighten them (use a pry bar or similar tool *carefully* to avoid damaging the tank). If broken, they'll need to be replaced.
* Obstructions: There could be something blocking the tank from seating fully. This could include debris, a loose bracket, or even a misplaced wire harness.
* Solution: Thoroughly check the area around the tank for any obstacles. Carefully remove any obstructions. Take your time and visually inspect everything.
* Fuel lines or electrical connectors are not properly connected: Failure to properly secure the fuel lines or the electrical connectors will restrict proper positioning of the tank.
* Solution: Ensure all fuel lines and the electrical connector are properly attached before attempting to lower the tank.
* Improper lowering technique: Trying to force the tank in can cause damage and hinder the process.
* Solution: Use a jack (ideally a floor jack with a suitable adapter to support the weight evenly) to carefully lower the tank. Support the tank's weight during the entire process. Avoid dropping or jarring the tank.
* Tank is damaged: The fuel tank itself might be damaged, hindering proper seating.
* Solution: Inspect the tank for any bends, dents, or cracks that could interfere with the installation. This is rare, but possible if the tank was dropped or significantly impacted during removal.
Tips for Reinstallation:
* Helper: Having a helper is highly recommended. One person can guide the tank while the other supports and aligns it.
* Jack Stands: Use jack stands to securely support the vehicle once it's lifted. Never work under a vehicle supported only by a jack.
* Patience: This is a potentially fiddly job. Don't rush it. Take your time and carefully check each step.
* Manual: Refer to a repair manual specific to your 1997 Lincoln Town Car. A manual will provide detailed instructions and diagrams. (You can often find these online via a search or at auto parts stores.)
* Photography: Before removing the tank, take pictures of the process. These can be very helpful during reinstallation.
If you're still having trouble:
* Professional Mechanic: If you've tried all of these steps and are still unable to install the fuel tank, it's best to take your car to a qualified mechanic. Attempting to force the tank could cause damage to the vehicle or the tank itself.
Remember safety first! Work in a well-ventilated area, and never work near an open flame or sparks while working with the fuel system. Disconnect the battery's negative terminal before starting any fuel system work.
