There yah go. Put a multiplier string in parallel with the bleeder 
string.  Using a calibration pot and zero center meter between the 
strings. Initially set it to zero. Call that the "condition" meter. 
However you might want to short out that meter during start up. Just one 
more meter for the panel to make it look complicated. Kinda like the 
panel in an airplane.  What do you use all these meters and gages for? 
Why to impress people! You don't really expect me to learn what all 
those things do, do you? <:-)) Welll...I do pay attention to the basics 
like oil pressure and the fuel gages.
