The aeration of fuel comes from the massive amount of returned fuel dumped back in the tank continuously, from their design.
Even the smallest 95gph LP is 10x+ what is possible for your truck to burn under the most extreme circumstances.
All of that unused fuel is dumped back in the tank.
While the Diesel we fill from the pump is aerated in the flow, filling a somewhat translucent yellow Diesel can, you can see how quickly the air dissipates at the top.
Point being, after your tank is filled, there is no air left in the fuel. The supply pickup is at the bottom, again avoiding any type of aeration at the tank top.
The sump is a fix for a problem created by the pump design itself, IMO.
A simple small LP added to the mix, delivers the volume needed, at the low psi the CP wants.
A JK deluxe kit (there are other options), 'bout 1/2 the $$.
Add a $30 filter head for an added aux FWS filter.
While your stock filter is designed as a FWS filter, it is most efficient at removing water, being pulled thru the filter. Which your stock CP does.
Adding a single LP to the mix, should also include an aux FWS filter before the pump, keeping a draw/pull thru it as the stock filter does without a LP.
I feel that the in-tank pump, would be counterproductive to removing water from the fuel. Any water in the fuel that the pump picks up, is then emulsified as it's pushed forward to the stock fuel filter, making it difficult to remove the water.
If my rambling on makes any sense...
You've dumped the CP4, and want to clean up your fuel and prolong your investment with the CP3 conversion. Positive pressure, FWS, and a quality fine particulate secondary filter.
That covers all the bases.
