Fuel is leaking from fuel line
How do i replace afuel line on a 1997 buck lesabre on 1997 Buick LeSabre
Are you certain it's the fuel line and not the fuel filter? If it is leaking or dripping near the fuel filter - replace the fuel filter first. If you have not replaced the fule filter in awhile, try that first. It's under the car, near the right rear passenger tire.
This kind of advice is best given after a visual inspection to determine what needs to be done. You may be able to repair i or it may need to be replaced.
