[Dsg-mvt] Request new manometer for Eel premix gas system + interlock

[Franck Sabatie]

Dear Marc,

It looks nearly empty (or am I reading this wrong?), which is odd : we only
use 7l/h, a new bottle should last 5-7 days. Maybe there is a leak
somewhere before or gas rack (we check input vs output flow).
