Optimum Fuel Pressure

Optimum Fuel Pressure
I know this is out there somewhere but i did a quick search and gave up. I finally bought the quick-lock tee to make my FP gauge functional. At start up i got straight to 13 psi, then at WOT or as close to WOT that i get, i drop between 11 & 12psi. Is this acceptable?
Also, changed my filter on Airdog for the first time, is it typical to have free flowing fuel when you are changing these? I unscrewed the B and got poured on until i put the new one back on.

well i have found a small leak in my connection to my gauge. have to take it back apart tonight and see what is going on. I skimmed through the manual for my airdog but did not read in detail about how to adjust the pressure. do you know if that is fairly simple?

the manual says its preset at 15psi +/- 2, it also says to change the pressure, the spring needs changed out. I am wondering if i am losing pressure to my gauge due to the leak? I didnt install a needle valve, i was told the isspro's would be fine without. Also, i just hooked up both ends of FP tube to the fittings, i didnt bleed any air or add silicone as the directions said to do. Is that an issue? I have only dealt with FP gauges on the fuel rail on gas engines.

ok so i took my pillar back apart and made sure the tube was seated and tightened with no leaks at the gauge. I checked the voltage and cleaned my power and ground connections. it jumped from 11-11.5 psi at idle to a shade over 12.
In the manual it says it is factory set at 15psi +/- 3psi. Did i just happen to get a -3psi setting? Is there any way to adjust the pressure other than buying the new spring or am i missing something that is making the gauge show a lower pressure?
