Default Need Help!!!

I have noticed a 3 psi drop in fuel pressure and also noticed that my AD 150 is making a louder higher pitched that usual. I swapped the ff and cleaned out the water seperator. I also took out the mesh screen before the water seperator and still nothing is helping. While i am going down the highway@ 70 i can floor it and suck the fuel pressure down to 10 psi. this Air Dog is only a few weeks old. What am I missing? The only thing i havent done is take the Air Dog apart.

thank in advance!

mine actually doesnt make a consistent high noise. its like it goes high for a few seconds and then i dont hear it for a few seconds. it keeps cycling like that, but the psi stays the same. I will call them and see what they say.
