Running fuel lines

I'm installing the new fuel valve.  It means I have to redo all the tubing to and from the fuel valve as the new valve is duplex, having a primary and return feed that goes back to the same tank it feeds from.  This is better on the pump and regulator and the preferred method by the injector manufacturer.  But it's not easy, and there's a lot of tubes to run all over.  I'm also adding a small inline fuel filter ahead of the valve for each tank.  This way, should one filter get contaminated, it won't clog the only filter I have and potentially switching tanks will provide clean fuel from the opposite tank.
