Fuel Leak?

[x10Hz]

Hi, my parents 07 cl9 AT just sprung a fuel leak, basically when you go to start it fuel starts to piss out at the rear end of the car. Its not leaking from the tank cos when the fuel pump is not running, there is not leak. Does anyone know what the problem might be, and how much/how to fix it?

Thanks

Lines pierced. Or a line came off.

Tow it to a dealer or mech shop. No point getting a quote over a forum without physically seeing the car. There is too many possibilities for a leak.
Breather, supply line, return line, fuel sender, fuel filler.

You know whats leaking, fuel. So tow it to a shop and tell them the problem. Theyll take care of the rest.
