High fuel pressure?

High fuel pressure?
I'm running the KE blue mech fuel pump on a warmed up 525sc. Boats inning really crappy today. Loading up.. stalling..
I have an electrical fuel pump gage on the dash and it was pegged over 10 psi. Anybody ever have an issue with these making too much pressure?

Haven’t run into any mech pump increasing psi, but others have. I’d do what was suggested above. If that doesn’t work, it is more likely the top section that has issue. The big spring on top of ghe diaphragm is what set’s fuel psi.
The bottom section of the pump has the one way valves the ‘in’ has and the ‘out.’ If these vslves have an issue, little or no fuel psi would be the outcome as fuel can reverse direction thru part of the stroke.
