I would consider making some changes. Please. With the loops in the suction lines where is a possibility of trapping air in the tops of the loops between the filter and the pump. Also excess tubing can pick up more heat from the tunnel and transfer it to the fuel. You'd be surprised at how low the fuel flow is in those 3/8" lines during cruise. Plenty of time for the fuel to get warm. I actually put Firesleeve on my fuel lines inside the tunnel. I just replaced my old style AFP pump with the new style, and by using a Phoeinx coupling available at Spruce I was able to keep the pump in line with the filter using the same hose clamp arrangement and only needed to fabricate a new line from the fuel valve to the inlet of the pump. Heating those lines on the suction side is only asking for trouble. If you were to get a vapor lock in one of those loops, there's a good chance that the suction from the pump would not be able to overcome it, resulting in fuel starvation to the engine.
Here's the fitting:

It's a lot shorter than you can make at home.
Also, you might consider moving the flow meter to the engine side, between the servo and the flow divider. The flow meter in the tunnel can be an issue with pressure drop on the suction side of the engine pump and incorrect or fluctuating readings in flight. When I moved mine after 1000 hours in the tunnel I was amazed at how much more accurate the sensor became, and it never changes with activation of the fuel pump.
