Is your 2 micron filter on the suction side ?
It is a 2 micron filter/water seperator. These filters are 30 GPH flow with a very low restriction. I'm running a second one up front just before the surge tank.

should be 100 micron before the pump. 85 maybe. but not 2! 10 micron after the pump is sufficiently small, but never run a fine filter before the pump. 30GPH sounds kind of small, considering most pumps will put out 100GPH or more.
It is on the small side, but according to the calculations I've found on-line, 30 GPH filtered down to 2 microns is sufficient for 400 hp with a BSFC of .45. My motor is only going to have about 300hp for a while.
I'll have to add another pre-filter and install a larger low-side pump when I upgrade the motor.
