I couldn’t help responding to Rob Wolf’s

 

“It is definitely interesting to see how the parts all interfere with each other. ...”

 

I though I was being clever to install all the large/heavy lines & hoses first on my IV-P, and then the smaller, more flexible ones then the wiring. I expect that this was better than a random approach, but it still didn’t eliminate the need to change things. I also used Sky Ranch hoses, but didn’t have the guts to tell them I messed up and had to change two of the 20+ hoses they sent me. …I just paid for two more…

 

One thing that I changed after the first routing was the clamping of engine hoses. Specifically, I was careful not to clamp/secure a hose that was running from one point on the engine to another to the firewall or engine mount at an intermediate point. Rationale is that the engine moves (quite a bit) independently from the mount, firewall and cowling. If you put an intermediate clamp to the engine mount (a handy choice), the hose flexes in at least two places when the engine moves. The alternative was to fabricate some hose mounting devices that could be secured directly to the engine, but I think the hoses will last longer for the effort. The related task was to be sure that hoses running from the engine to fixed points on the mount or firewall had plenty of slack to flex, and were not intermediately clamped to the mount or firewall with too short a lead to the engine.  Just another thing to think about…
