Curious as if there is an operational reason/advantage to having the tee at the engine fuel pump running to the sensor or if it would be possible to put the tee after the flow sensor to reduce the length of hose.
The T fitting that connects to the mechanical fuel pump is designed for the Lycoming engine and works very nice. But keep in mind, there's are probably a 'zillion' other ways you can route your hoses, or mount accessories on the firewall. This system is designed around where I mounted components on the firewall in a logical path, as well as where I could find room on the firewall! This is only one of many possible solution for running fuel and oil hoses. I worked with Steve at Aircraft Specialty to take this system, and make it available to other who want a plug-and-play solution. Keep in mind that this is not the only way to install hoses and components. If you, or any one else, wants to mount things in different locations, Aircraft Specialty can easily make hoses that fit your installation. Just e-mail Steve and give him the lengths of hoses and he will make you professional, firesleeved, and pressure tested hoses!
@@KitplaneEnthusiast it definitely makes sense to retain the lycoming piece. Those blocks you have for the transducers are a very nice piece as well. Thanks!
Your question would be better answered by contacting Aircraft Specialty. The hoses are fire sleeves so they are able to withstand fire for probably a specified amount of time. There’s certainly no worry with them being in the engine compartment.
Any clue as to why you would add weight and complexity in remote mounting oil pressure and fuel pressure sensors when they can be installed directly at the source with no hose or manifold?
Yes I do have a clue. I added complexity and weight because I followed the manufacturers instructions on how to mount them. Good luck on your Bearhawk build. Hope you follow the instructions.
@@KitplaneEnthusiast thank you for the response. I was looking for the technical reason ( I am an engineer for which I apologize). Vibration, ease of maintenance, etc. I will contact the manufacturer to see why. If it is just an ease of maintenance thing I will likely omit it. Thanks again.
There were two reasons why. For a year and a half Lycoming told me they wanted to sponsor my engine. After numerous phone meetings with their advertising department, they promised to sponsor an engine, so I never ordered an engine to get on their two-year waiting list. When it came time to actually provide an engine, Lycoming ghosted me. Even speaking with the reps, I was still debating between fuel injected and carb. Based on the trouble I have with hot starts in the Pitts, I wanted to avoid the hot start issue in a bush plane which will probably see numerous starts during a day of flying. So I was leaning towards the carb. When Lycoming ghosted me, I discovered that Zenith actually had two engines in stock. Both engines were set up with the carb so that made my decision easy. I immediately ordered one of the engines from Zenith.
Well your just an all around good dude eh!!...thanks for the reply..have a Merry Christmas eh!!..
Oh...hoses...gives me chills..lol..great video as always..
Beautiful. Great resource for builders.
Beautiful and a great description with excellent video of this job. Thanks.
Clean
I’ll order later today!

Merry Christmas Mark from Sydney Australia. Do you have max operating temp for the orange hose, that makes up your kit.
Merry Christmas

Will those fuel and oil lines to the sensors self purge of air, once you start running the engine, or do you need to do that at some point?

Mark, what is the reason you chose a carbureted engine instead of a Fuel injected one?
Believe it was availability. Mark has another video about that somewhere.
I thought it was because of hot starts with fuel injected..can t wait to find out...
