Re: u think ur smart then help me (demelok)
Duct tape is not pressure rated, and definitely does not stand up to fuel well. If the leak is in the engine bay, you are playing with fire (potentially). Tell us where the leak is, and we can give you better suggestions. Injector? Cold start valve? Fuel distributor? DPR? Accumulator? Fuel line to pump main?
You might be able to fix it yourself and save yourself the dealership cost.
