This is part 2 of the 3 part presentation on upgrading the Racor Winn fuel system to the new 790R30 filter system. This section deal with the Golden-Rod filter addition that is before the Racor filter. I added a T connection to the Racor Filter output line to add a vacuum gauge. An alternative would be to use the opposite/redundant output port on the Racor Filter and plumb that for the gauge. Racor makes remote sensors for checking the state of the filter but they are almost as expensive as the filter unit so I used a gauge. At the end of the narrative there is a 6 min video showing the filter in static and with the engine running with an explanation of the operation.
