Based on some advice from a few other builders, I relocated the “red cube” (the fuel flow meter) from the Vans recommended position to the engine mount. The Vans location is above the exhaust, and other builders have complained of excessive heat and vibration causing the units to fail. The fix is easy – switch the fuel lines – and the cube is perfectly positioned above the engine mount. By switching the fuel lines, I mean the line from the fuel pump to the red cube is switched with the line from the red cube to the fuel controller.
My mount is not the most robust, but I think it’s sufficient. A single bolt holds the unit onto a cushion clamp that holds the engine mount. If the clamp ever failed, the fuel lines themselves would keep it suspended. However, it would probably cause some damage in the process. A better solution might be designing a bracket that has two clamps, which is something I’ll look at down the road.
