I am getting a big fluctuation on my fuel pressure indication on my last flight. For the experts out here, could this be an indication the fuel pump is about to go bad or this could be a probe sensor not working right.

Engine seems to be running pretty smooth.

Here's a link to a video where shows the fuel PSI fluctuation.

Any ideas?
