I am planning on using Motorola sensors (MPX5700) to read the intake
manifold and turbo output.  I am a bit confused about the type of sensor
to use.

I believe that I should use an Absolute sensor for the intake plenum and
a Gauge sensor for the turbo pressure ---But I am not sure!  
The meters will be calibrated to read in inches.

Can someone comment on this --- Ed and Tracy probably know about this.

Also, has anyone ever used these sensors to read fuel pressure, are they
resistant to fuels?

Thanks
