Line from Servo to Spider FM-200

Kyle Boatright

Well Known Member
I'm confounded on a best practice for routing the fuel line from the servo to the spider on my FM-200/RV-10.

In my case, the line exits the aft side of the servo, wraps up around the right side of the sump, then through a grommet on the inter-cylinder baffle between #3 & #5, then to the spider.

The geometry where it goes through the inter-cylinder baffle creates a significant bend in the line to clear the oil sump flange. The geometry also pushes the line up against (or very near) one of the sump bolts. I worry about vibration/abrasion of the fuel hose there. I'd love to use an adel clamp on the sump bolt to secure the line, but the geometry doesn't work for an adel clamp.

Any experience here? Here's a picture if it helps:

 
I secured it to the sump bolt with a little bracket and an adel clamp.

Kyle - will try to take a photo when i get up to the hangar today. Lycoming installed of it for me and did what Todd shows. Basically a small bracket that is just a piece of twisted metal with an Adel clamp.
 
Kyle----Similar to Todds, or if you want to get creative, even something like what Dan Horton did with his flow transducer install----just supporting the hose and not the cube.

Not my plane but another option for routing that fuel line. It runs above the sump aft and then turns down.
