Default Re: Changing out a 912 80 HP in a model IV

I moved my firewall penetration to the right side, mostly to reduce heat load on the fuel, but also to make it easy to access. The primary fuel line runs forward along centerline to the base of the firewall, then right in front of the pedals, then up along the edge of the firewall, then penetrates the top of the footwell. It's then a super-easy route to the fuel pump. Thousands of words attached.

Thanks Guy! My hard fuel line comes up to the right side of the Firewall and then crosses to the center where it penetrates. I think I can easily modify the penetration point to mimic yours. I"ll look in the other "words" you sent and see if I have some blueprints of the other connections I.E. gascolator, aux pump and the like to get an idea of routing. My current penetration on the firewall puts about 5 hose clamps at junctions near the stator assembly. Yikes!

I see that there may be some fuel lines and push on fittings available in metric sizes as well as Banjo fitting. I think I can nearly duplicate the hose assembly that came with the engine and now it will reach my outboard facing carbs. (model IV needs to switch left and right carbs and manifolds)

I'm looking to source the silicone hose for fuel lines and not finding any. I could use Gates or other fuel hose, but I like the removal of the 5 year rubber replacement by using the silicone stuff. Anyone got any Ideas?

As I learned on this great forum you don't have to swap the carburetors for a model 4. Just swap the manifolds.

Keep the throttle & choke connections on the outboard sides for easy adjustment / synchronization.

This is a pic of how the 912 UL comes from the factory. the Next pic is how its mounted to the aircraft. I couldn't figure out how to get a picture to a private message. Sorry. Anyway, the carbs have to be switched from the manifolds as well as the manifolds from the left and right side, or the throttle and choke are inboard.
Step 1. switch manifolds. (now the carbs are on the wrong side.)
Step 2. correct step one.

Just looking at your pictures, Guy, I think I saw a spot you didn't polish...

Seriously, that is one gorgeous plane!

I thought the same thing! You know he's dedicated to polish when the aluminum fuel lines have a mirror finish.

Here is an Idea I am toying with. Any and all thoughts are welcome. It will have banjo fittings on the carbs but everything else that isn't on the fuel block/manifold will have a barbed hose fitting and a clamp. All will be firesleeved.

Oh and thanks for the kind words, you guys. You know how it is, if you polish just one thing, then everything has to be polished. Them's the rules.
