Hi Bill,
  Yes, the senders should be the same type.  The VDO senders have been found
to be unreliable so I now recommend using a specific Stewart Warner sender
 (out of town so I don't have PN with me)  The EM2 has to be updated to work
with the new type if it hasn't been done already.  But your 2 sender setup
should work fine.

I have found that the pressure after the sensor will go down on a high
throttle runup if the filter is getting clogged so I do this rather than
install a second sensor.
