Roger:

I don't have a fuel pressure sender, just a pressure gauge directly attached to the fuel rail. It reads fuel pressure directly from the fuel rail as a test gauge would do. It is easy to take out, but I don't have anything to check the calibration. Long ago, I used to check these types of gauge with a dead weight gauge tester, but don't have access to any calibration equipment.

What would you suggest to calibrate the pressure gauge?

Hi Doug,

If you only have a gauge then it is a little less likely an issue, but it still could be. You absolutely need a restrictor in the fuel gauge line or it will fluctuate. I'm not sure if Tecnam has a restrictor in line or not. It should be easy to check. It should be at one end or the other of the line. If not it is easy to buy and install one.
