i cant speak for other electric pumps, but the metric mind pump has rubber feet i have mine in the trunk, with the deck lid open i hear the fuel pump not the vacuum pump, its been in the trunk for 3 years, the first year a fuse blew,
since then no sound no issues. go to their web site and read, it lists what
DB's the pump puts out, its made in switzerland, need i say more?
