This morning I walk into my garage and I heard a clicking coming from my machine. Turns out it’s coming from fuel rail. Key is off and when I unplug the harness at the tank it stops and my lights turn on. Key off as well. It doesn’t do it constantly, it’s intermittent but time isn’t a factor, I assume it did this off and on all night last night. Any ideas? Voltage regulator? I have about 1k miles. 2015 900s

Here’s a link to the pump noise.

Thanks
