Hi there:

Without being there to physically inspect your Mazda, it’s impossible for us to tell you what is causing your fuel leak. If it’s with the fuel rail however, you should take the time to replace the entire rail, as if one o-ring is faulty or the rail is cracked, it will continue to have problems over time. If you need someone to help you diagnose this issue, contact a mobile mechanic from our team to {complete a fuel system inspection](https://www.yourmechanic.com/services/car-is-slow-to-accelerate-inspection).
