TL;DR - new/redesigned pump seems to have fixed crickets for me at least.

Different fuel and temperatures have different results. It may not be the pump that changed you just hit on the right combo. E85 has been very rare in causing crickets so you have yet another variable in the mix. In order to say without a doubt that the pump changed anything you would need to run all different brands of fuel through it at varying temperatures.
I can make mine come and go at will by using certain fuels at specific times of year.
