Fuel, by the very nature of going through high compression, is going to heat up even before it carries away heat from the pump.
Note --- remember Bosch patent to isolate pump from engine to reduce heat transfer?
If you heat up the fuel in the tank via the return hose, it will tend to become hydroscopic and whatever moisture in the tank that is separated will diffuse / be absorbed into the fuel up to the maximum non-emulsified water capacity of the fluid for that temperature.
When it cools down, it will either lose the moisture by letting it drop out, or more likely, become a super-saturated solution that can turn into a emulsion with some shaking / vibration.
That can create an emulsification that may not be filtered out.
Need to know whether a water blocking membrane (usually a polymer) will block water in emulsion vs. water.
Is the Ford filter equipped with a water blocking membrane?
GM?
