RE: CM2350 Code 4727 While watching fuel pressure desired versus actual it always looked normal until the the truck is in fuel cut. The pressure relief was changed by the dealer when the pump head was done. That relief valve certainly could be opening and that is why it holds 42k psi and stops climbing. I recently had a truck with a valve opening at @38-39k psi that was causing the truck to pop a code and derate so I know that relief opening is higher. | |||
