Tips
- Be careful not to drop the fuel tank sending unit into the fuel tank.
- If you are unable to remove the old seal with a flat-head screwdriver, you can use a pair of pliers to gently pry it out.
- Be sure to apply a thin coat of petroleum jelly to the new seal before installing it. This will help it to go in easier and prevent it from leaking.
