RE: CM2350 Code 4727

Fuel rail leak-down rate isn't supposed to be more 4,000 psi in a minute... Ideally you don't want to see a greater drop than 2,000 psi in a minute.. Assuming you replaced the pressure relief valve first... Re-tighten your injector tubes and all your fuel lines and repeat, if it persists start capping the fuel lines until you find the offending cylinder(s)..
