WOT and fuel pump issues

i just put an secondary gauge on my fuel rail and it reads 6.5. the one on the reg dopes down to 5. the gauge on the reg is a summit and liquid filled while the other is a mr gasket not liquid filled.. ill keep an eye on both. really dont want to rip my pump or reg apart but if i have to i will if i see my secondary drop down..

bending the pedal helped and not i get WOT
