I need a diagram of how the fuel lines and evap lines are actually ran on the vehicle listed above slt 1500 non Denali that I am working on.
Someone prior to me worked on this vehicle and did a hobb cobb job to it. The fuel lines are broke and disconnected and he has other hoses and what not hooked up his own way. He even used a air hose to run a return line but it goes to the vent tube on the tank by the fill tube and ia mow leaking gas very badly.
If you can help me with this ladies vehicle I would highly appreciate it.
Thank you in advance.

Hi Bruce,

I always enjoy correcting a poor quality repair attempt. I have attached some images of the EVAP and fuel routing. Please let me know if this helps.

Here is a guide on EVAP basics that will help get the system reset once your repair is complete:

Hope you get it sorted,
