I assume those may be the fuel return lines, so around the intake you may see some other cut hoses as well...? Or perhaps, near the engine, the return was just looped back in to the supply line somehow...? It is even possible this engine did not come with a fuel return line so the lines from the tank were disregarded.
I really hate the design of those shackle hangers! At the very least, I would make a brace of some sort to join them. Or preferably flip the shackles...? Not trying to get in your face; just ideas cuz I wouldn't trust them.
For the record, I love this thing, it just needs some serious porn star love.![]()
