My Bad, you couldn't see my tongue-in-cheek.  I was pretty sure it would stop the engine.   The serious part of the question was what happens to the pressure reading on the monitor.  If the reading goes down, the problem is probably the regulator and not instrumentation.  And even then it may not be a problem.  the regulator may being pushed beyond its design maximum flow rate.

Hmmmm...  Mine goes up about a pound when I switch on the second pump.  What happens when you turn both off?

Question about fuel pressure indications, at fast idle 2200 RPM, fuel pressure is 42 PSI on EM2, if I switch on the back-up pump with the primary pump the pressure drops to 35 PSI, can here both pumps running, if I switch off either pump pressure goes back to 42 PSI.  My system is 13B, stock red injectors all four, pressure regulator is stock Mazda on the end of fuel rail with vacume connection from dynamic chamber.  Thanks,  David R.
