Re: [DML] Noisy fuel pump (still!) (and again!)

A suction hose can never operate at higher than atmospheric pressure - ie vacuum is not a
force in its own right, it is merely a lower pressure than the outside. In this case,
atmospheric pressure.You are unlikely to create vacuum bubbles at this level of suction
and even if you did, they'd disappear the moment they pass through the pump.
