Now that we have "most" of the windscreen and skylight work out of the way, we moved back to more firewall forward work. We've been fighting with the water pump elbow on the Rotax 912iS engine. No matter where it is placed, the engine Ring Mount interfered. Luckily Edge Performance in Norway has come up with a solution that works well. They provide an extension section that moves the elbow out away from the engine allowing you to route your coolant hose around the Ring Mount.

We also decided to make new oil and fuel hoses. We had originally planned to use some high-performance light weight racing hose, but after many attempts doing pressure testing on the hose assemblies, we could never eliminate a very slow leak. We switched gears and are using a more standard hose. Luckily, since the previous hoses were already made we just had to duplicate the lengths for the new hose assemblies. Took us a whole day to make the new hoses, but much more pleased with the outcome!
To try and clean up the firewall forward, Mike designed some hose organizers and 3D printed them. They came out well and help organize and route the hose lines over the engine.

We also wheeled the airplane outside for a few "glamour" shots in the sunshine. We've made a lot of progress since the last time it was outside.
