Tandem PS pump from MBPumps

[ds190]

I need a replacement tandem power steering pump for my 91 300TE. The hydraulic pump component is not pumping hydraulic fluid anymore.

A used one from PGA is $150. A new one is $700-800.

A group in Las Vegas called MBPumps sells a rebuild one for $200, with a $150 core charge. He will send it COD, and I return mine to them.

Anybody dealt with MBPumps?

Thanks, Dave
