JD's Trafic Campervan Conversion Ep12 - Diesel Heater Install - Soundproof Fuel Pump?

Can I sound proof my Fuel Pump?
This is my Diesel Heater installation.
Again, a job I found a bit nerve racking, but thanks to the 'TH-cam University' I eventually felt confident to give it a go.
It actually went pretty smoothly and I'm happy with how it turned out. The lowest power setting seems more than enough for me.
If you've any helpful notes/advice on this stuff - by all means let us know.
See you down the road....
