I've seen another person on Spool Street complain regarding the same ticking noise. Have you reached out to Spool to see if this is "expected" behavior.

Another issue i'm experiencing is a faint ticking noise that is RPM dependant which we (me and David) suspect to be the HPFP since i noticed it around the time we installed the pump.
I have not dug into this further, and it being the hpfp is just an assumption, can be something else entirely, will report back once i know more, but would love to hear other's experiences with it.

I don't think any material outside/around the pump will help. The ticking sound I'm hearing with the FX-150 is being transmitted through the engine itself. The sound under the hood seems to be largely unchanged.
It may be possible to get used to it but any passenger or other human is going to think something is broken under the hood.
