I've now spent 3-4 hours trying to package fuel lines in the wing root and all I have to show for it is a bunch of wasted tubing and a list of what won't work. Decided to change course and put the fuel filters in the middle of the line under the forward covers. It'll be messier to inspect/clean them there but it's easier to work there than in the wing root and there are fewer bends in the supply line.
The issue I have now is trying to get the return lines connected. With the wings on I can't put anything too crazy in place so I'm trying to work with what's there; I did a poor job locating the return fittings and what worked in my head isn't working in reality (which is why I like to work in CAD for these sorts of things).
The only viable way I can see to get something in place is to put some sort of separable union in the wing root. My thought was an elbow right after the line comes out of the fuselage, pointing forward. Then the return can come forward, up and out to the tank.
I'm doing everything I can to avoid hard 90s on the supply end, including a custom fuel valve mount solution, but I can't see any reason why one or two hard 90s on the return side should be an issue. Is there anything I'm not thinking of?
