I replaced my fuel pump with the newer model from Rotax, and now my pressure gauge on the D-180 reads up in the yellow range. I seem to recall seeing somewhere on an older post that there are new settings for the newer pump but I?ll be darned if I can find them. Can somebody point me in the right direction?

Have a look at post 43 in the following thread. I think it has the info you are looking for.

Hi John --
The updated fuel pressure spec is in the ROTAX 912 Installation Manual (https://www.rotax-owner.com/en/support-topmenu/engine-manuals#912-series-engines) in Section 73-00-00 (Page 5). The range is 2.2 - 7.26 psi.
