https://www.rotax-owner.com/en/videos-topmenu/elearning-videos/231-914press136 shows a nice video walking through the process of how to adjust the fuel pressure regulator.

The reality is that the upper side is easily visible, but the regulator adjustment is on the lower side:


So getting at it looks more like this:


How is this done in real life? Is there a way to snake tools at it from underneath, maybe with an extremely long slotted screwdriver?

    There's no easy way to do it without growing an extra elbow and arm.

    An alternative method is to remove the bolts that secure the regulator to the airbox, allowing for better access to the adjustment screw on the bottom. Keep in mind that every aircraft installation is unique, with varying levels of accessibility. Consequently, providing precise instructions for reaching that screw can be challenging, as it may not be applicable to all aircraft configurations.

    In some situations, you might need two people to perform this adjustment—one working on the nut and the other on the screw, possibly using a very long flat-blade screwdriver.

    It's crucial to carefully follow the video instructions when making adjustments to the regulator, as proper calibration is essential.
