Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

If the noise is coming from the fuel line then have the shop install a fuel pressure gauge and monitor the fuel pressure to make sure its not excessive. Normal pressure should be right at 56 yo 60 PSI. If the pressure checks okay and the fuel retun system is okay then there really is no reason the line should be making any noise.
