Fuel-Related Engine Shutdowns

Under tech tips there is a reference to fuel pumps becoming "cavitated." What happens when a fuel pump becomes "cavitated?"
Is it rendered nonfunctional?
If still functional what can be done to "decavitate" the fuel pump?

It's talking about air pockets developing inside the pump from leaks upstream from the pump. Consider it a generic term as our pumps, both electric and mechanical, do not have rotating impellers.

Is the solution simply pressurizing the fuel system (w/ a fuel line bulb pump) to eliminate the cavitation (i.e., air pockets)?

The solution is to find and fix the leak that introduced the air into the system. Finding the leak can be tricky because the pressure gradient is vacuum. Fuel doesn't leak out, air leaks in. Hose fittings, filter gaskets, things like that are the usual suspects.
