The reason it leaks is the fuel pump is under pressure when you turn on the key and will pump the fuel out of where ever it is leaking. Do not drive it till the leak is found and fixed. If you need help with this, a technician from YourMechanic can come to your home or office to detect the leak and make an appropriate repair.
