Body fuel/brake hard lines

Hi all,
Anyone have a labelled diagram or images of which hard line is which among the four that run under the car? I know ones a brake line (far left I believe), then the other three are fuel feed, return, and vapor, but I don't know which is which (without crawling under the car and taking stuff off, which i don't have facility to do at the moment).

Thanks

Yes, so "Z" (furthest left except for the brake line is the fuel feed?

Right, the brake line sits in the empty slot in the diagram (driver's side, the plastic clips all have four slots), I just need to know which of the three pictured is the fuel feed. I believe it is Z?

Z (the hose leaving the fuel filter) appears to be fed from the fuel tank via the left most hard line up to the fuel tank. Top diagram.
Then it appears to route to the right most hard line to the engine bay. Bottom diagram

Yes, right most in the diagram, which would be driver's side (left) of the car, with the brake line being the furthest to the driver's side (left) of the car.

So, the current brake line sits right next to (my) unused fuel feed. My plan is to use a second brake line clipped in where the fuel feed was to create a 4-channel system for the MK60.

I’m sure you remember from previous discussions, but …

Fedhill brake line - Where to buy brake line, fuel line, brake line flaring tools, brake line nuts and brake line fittings

cheaper on Summit Racing etc. but they address the lower cost products in the link.

Gracias. The plan is to not really have to fab new lines, but for a few custom flex lines to connect everything.

the general recommendation is to have the minimum amount of flex line in the system as possible, but best wishes.

Where I'm planning to mount the unit, I need to be able to loosen it and pull move it (within reason) to access other things beneath it or to be able to remove the computer to be reprogrammed off site without opening the fluid system, so flex lines become a necessity, though the location means none will be more than 18" long, most less.
