I had bought the pump some time ago, but fell into the "if it ain't broke..." mentality. But it was time to start on my second rubber parts replacement and I figured with the fuel lines it would make sense to do the new pump at the same time. Also installed the drain line as required.
I just finished with the fuel lines today, and have not done a runup yet. But something in the SB is just a tad unclear...

My POH shows the acceptable fuel pressure range to be from 2.2 to 5.8 psi. Here's how my gauge is marked:

In the latest ROTAX 912 Owners Manual I can find, it still says 2.2-5.8 psi, but then parenthetically says the high end is 7.26 psi "Applicable only for fuel pump from s/n 11.0036".
Am I correct in assuming that includes my new style fuel pump? I don't have the s/n here to check. If so, rather than try to remark the fuel pressure gauge, I'll just add a small placard with the new max psi.
Tomorrow when I do the runup I'll check the fuel pressure for any change and get the s/n of my pump.
