hzj79 sub tank line routing, need a visit to dealership

[rick_d]

So I am sitting in sunny Arizona with a hand full of fuel lines that eventually traveling back and forth from the engine bay to the main tank and sub tank. I need someone (maybe Australia hint) to drop by a dealership to look at a cab chassis truck and see how the lines route and maybe take a couple photos. The images on parts docs are a little unclear and do not show especially the areas near the exhaust crossover.

the primary lines are on frame

the secondary line I don't have and will have to make

the tertiary lines are a triple set starting somewhere near the left side of main tank then migrating back to pick up on right side of sub (rear) tank. The frame I have here has brake lines and wire harness passing through the frame crossmember behind the main tank and I need to know if the three lines (supply, return, vent) also go through this same hole. I see the supply and return lines then cross over to left side of truck on this same crossmember?. The vent line stays on right frame and terminates somewhere near the filler neck.

So if someone can shoot a photo straight down from back of cab with good light I think I can make this out.

thanks in advance.

I'm nowhere near my ute but I do have some old pics I took.

And fuel cooler

Thats all I got for the 79. You didn't mention if it was wide or narrow front. This is for wide.

 

[rick_d]

it is wide front, but know that the switching valves are on top of frame rail just on left just forward of main fuel tank. There are many pieces here that are not seen on system i have seen (and am working with). The crossover heat shield might be a hint. let me do some digging

Hmmm. Sounds like the 1hz fuel lines are different to the 1vd ftv.

 

[rick_d]

this is what i see.

Found this on the net.

 

[rick_d]

found this, but vdj

here only the brake lines pass through hole. The bends of the late-wide hzj may sit in the crossmember on the rear side and cross over here. Still trying to figure this out but I am sure the switching valve is on left frame rail just even with front of main tank under the cab and not on the frame at crossover seen here.
