Is said material inside the pump or external?
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.
