Sneaky plumbing to run two 35mm stainless pipes through the tunnel alongside the exhaust.
To get past the narrow bit at the front of the tunnel and to dodge the gear linkage and exhaust, we need to go into some short sections of 40x20.
This seems to be a fair starting point. The pipes are held together with tape and cable ties while working out the best orientation.
Some bits of the 40x20 chopped into bits to make some L brackets to hold the pipes together.
Some long M8 bolts make make good height adjustable hangers to get the pipes sitting just right.
Now comes the fun of starting some suitable wiggles to get past the engine.
More bends and a transition back to 35mm round.
With a few more little kinks and bends we are to the front of the gearbox.
More to follow as we need to get the other pipe to follow this route, then sort out how we get both pipes to the boot radiator :)
