We have changed the design (TODAY) of the PS-1002 sping used in the return port of the FASS (Not HPFP). This spring now sticks pressure at 14 PSI. This was tested in my personal truck with KOER and KOEO. If you want to be around this pressure, contact your dealer (Not me) to get this spring. Ask for the PS-1002 14psi spring.
