I posted about this in my build thread but in hindsight I don't expect it's going to get a whole lot of traffic there, so I'll repost this portion here.
As I'm using EFI my fuel lines just need to go to the top of the engine; they don't need to run down to the intake first. I'd like to keep the lines away from the exit air and exhaust pipes, so I was thinking I could run them up on the back side of the firewall first and have the supply line exit on one side and the return on the other; hoses could follow the engine mount up to the back of the engine and then to the distribution manifold.
I had a whole bunch of 1/4 3003 tubing laying around with no specific use for it, so I decided to mock up a line (visible below) and use it as a template. The final line would probably be stainless 3/8. I think I can keep it tight enough to the firewall that the rudder pedals won't hit it even at full deflection and fully forward mounting. Return lines would basically mirror this on the left side.
The routing in the picture behind the firewall shows about what I'm thinking, though I think I'd have the exit come an inch or two further outboard (where the small sharpie circle is upper right; the one below the angle extrusion is where the brake reservoir penetration is per b/p) to avoid the brake reservoir if I decide to stick with that location. The bottom picture shows the proposed exit location from that side; a bulkhead. Line supports would be little brackets with P-clamps, screw tab facing aft. Thoughts welcome.
