How do I stop a leak at the fuel filter? on 2000 Mercury Grand Marquis

Leaking gas from the fuel filter.

Either bolt on line is striped or wrong filter, or just not tight enough,. Unbolt line and try to re bolt again keeping threads aligned. Before doing that wrap white lithium tape around bolt threads first. Usually a savior that tape. :-)
