Randy,

I agree with Mike, and wouldn't suspect the filter unless it was 3 or 4 times older than the pump. When the brushes get worn way down they don't have the normal contact pressure, which can lead to arcing and burnt spots that cause pressure fluctuations.

The Regina pressure specs ate the same a LH 2.4

36.5 psi at warm idle with vac hose connected
43.5 psi with vac hose pulled and plugged (simulating WOT)
