Fuel System Diagram

[Denio24]

Could anyone post a fuel system diagram who has the factory service information? I'm looking for a diagram that shows how the fuel system works, components, and visual diagrams.

Thanks. That's way better than the diagram I was working off of.

I just took what was on those separate pages in the link provided by Brundy and made it into one image for those looking for this diagram.

Where exactly does the Restrictor sit on the vehicle?

It’s in the hard lines. Its part of it. I believe there was one guy on the MKV forums that drilled it out.

Not sure there is any benefit from doing that. It helps to minimize pulses in the fuel system.

Right where the flexible fuel line goes into the hard line on top of the manifold. I drilled mine out and had no adverse effects.

Did you notice any flow or pressure improvement for doing this?

I haven't turned it up enough to know yet.
