1985 300D Turbo Vacuum Pump
How much vacuum should the pump pull in inches? This is a very very nice vehicle with 145,000 mi. The pump will pull 25in. @ a cold idle & 27in. @ 2,000rpm! But when @ operating temp. 23in. idle & 25in. @ 2,000 rpm! Should I repace the pump?? All of the vacuum consumers operate slowly when @ operating temp, but they do operate! HELP!!!!!!!!!</P>

Yeah! Thanks TOM!</P>
Every vaccum consumer was slow & @ times wouldn't operate @ all. Everthing operates better than ever now! Don't really know what I done, except checked all connections in engine compartment. Maybe dislodged a check valve?????</P>
THANKS!</P>
