KITPLANES Firewall Forward: What You Should Know About Hoses

[@texan2560]

A game changer for me was switching rubber hoses out for lifetime teflon hoses. You can order them to exact lengths needed. People do not realize that any rubber hoses need to be replaced each time every 5 years or sooner. And you cannot see the rubber on fuel hoses when they are covered by steel braid and fire block orange insulator. But when you take the hoses apart, and try and bend them, they are as hard as a ...... (you fill in the blanks with your favorite saying from your mechanic). Go complete Teflon hoses in your engine compartment.

Best series going ,👍

Very nice overview. In think O-ring boss ports are also worth mentioning, especially that they take a specific chamfer (than can be obtained with a specialized cutter) to work properly.

Nice video. Pity when you refer to Lycoming and Continental pterodactyl engines.

I can see in this video, there are a few no-nos if you believe what you read on vansairforce. A few no-nos are using zip ties in the firewall forward, not pointing the wire in the Redcube upward, tieing the ziptie to the engine mount. I used zipties and I mounted the Redcube to where I found it easiest to maintain. I also found early on, I ended up removing the bolts or fittings multiple times so using the torque seal is a waste and it doesn't tell me anything because I ended up removing the torque seal every time I removed the fitting.

The zip ties you see against the engine mounts are all GripLock ties, which have silicone padding on the ID. EI's guidance on the Red Cube says don't install with the wires pointing straight down and that it's "better" if you have the wires pointing up. This particular installation works really well, with highly repeatable readings.

I sometimes see oil coolers mounted in an orientation that will trap air. This one is probably filled only about 60% with oil and has 40% of the upper volume containing trapped air. Even if it was manually filled with oil before/during installation, if any bubbles are introduced to the system later, they will be trapped above the fittings. I’m interested in learning how this is ok.?.

[@KitplanesMagazine]

It doesn't trap air. The system is under pressure from the supply end.
