Frankly I am not bothered by the crickets, I've kind of grown used to them so I would not bother trying the new pump unless my current pump fails. I am very interested though in whether it gets rid of the crickets from a curiosity standpoint!
I am not convinced it would work or at least not properly. Both the cam and the pump were changed to work together. If the new pump is used with the old cam there could be too much lift since the old ones (according to the info) had a longer stroke. Of course the reduced cam lift could make up for that but things are deviating from the design specs in at least two areas so I would not try it. Sure sombody will at some point though and then we will know for sure.
