Fuel Line Routing

[skelrad]

Titan IO-340 with Airflow Performance FM-150 servo and crossover exhaust. What's a typical route to take for the fuel line going up to the spider? Where it exits between the cylinders takes it into the tight space between the sump and the exhaust. Based on the length of the fuel line provided, I'm guessing that's the route Titan assumes, but it seems awfully close to the exhaust (would probably work fine without the crossover exhaust). I could make some sort of an offset bracket clamped to the intake tube to keep the line from actually touching the exhaust, but it'd still only be a half an inch away or so. How close is too close?

Looking for some guidance on this fuel line routing. I'm not sure how close is too close when it comes to fuel lines and exhaust. I was hoping to get away without having to order a different fuel line, but that might just be wishful thinking.

Ground running is hotter than in flight. Your fire sleeve slows the heating process. Once airborne it gets quite windy. If an extended ground run happens you might experience symptoms of fuel boiling, full rich and more throttle should push cooler fuel through. You will need to decide if you're comfortable with this

I think if you deked the fuel line behind and over the intake pipe you would solve the problem. Based on the picture (hard to tell for sure) the existing fuel line may be long enough. I wouldn't like the fuel line that close to the exhaust. At the very least a heat shield clamped to the exhaust pipe between the it and the fuel line should be installed, although that wouldn't be my first choice.
