Anytime you pre-fill the filters, you risk introducing contamination into the system. By installing dry, the fuel must come from the tank and pass through the filter material so no chance of anything getting into the injection pump. I leave the secondary a little loose on our Detroit as it's then easier to use the hand primer to fill both. A plastic bag and paper towel cleans everything up nicely. Installing dry on the Detroit works well too but more effort on the hand pump as it's frame mounted and requires a little twisting to get it primed.
