Detail of conduit routing between engine and firewall. The white hose is the vacuum line to the vacuum pump seen with the blue stripes. We will replace this with a metal line in the future for improved durability.The steel braided lines carry oil first to the nose oil cooler, then back to the wingroot cooler, t hen back to the engine. The black rubber hose is the return line from the oil-air seperator. Notice the magento wires are held neatly together with plastic braiding. The Jeff Rose electronic ignition timing unit is the rectangular box just below the vacuum pump. The white oil filter is seen sticking out to the left.
