I have a walbro 255lph high pressure fuel pump, new stock fuel filter, -6an lines from the filter to the rail, AEM Fuel rail, -6an line from rail to fuel pressure reg, then stock return line. I cannot get my fuel pressure to adjust below 55psi with the hose connected, and it will not go bellow 62psi with the vaccume line off... It easily adjust up, but it only comes down so far... Any ideas would be appreciated... thanks
