Only if the flow to the orifice is constant.  The vanes of the pump wear and 
so fuel to the orifice is decreased in time.  Flow through the orifice could 
be the same even with a worn vane pump if the orifice is worn larger.  So even 
with exact same flow rate, the internal pressure could be remarkably less.  
Yes, no?
