here is some more related info...
quickserv says on the 553 fault ...
Quote:Shoptalk
A fuel pump actuator with excessive leakage or a damaged inboard o-ring will result in high fuel rail pressures at idle or light load.
==============
The second fault is the "Return Line" fuel excessive fault. -== Too much fuel is flowing thru the fuel return lines. It is a common problem when a fuel system component is leaky and causing back-pressure in the return line(s). This is usually leaky injector or pressure relief valve bleeding too much fuel etc. Could also be failed o-rings for the injectors or crack in the head. Could be faulty sensor, could be faulty pressure regulator on back of fuel pump, or other issues. Could even be a restricted return fuel line. And obviously, it could be the result of the over-pressure, the relief valve working its arsse off due to excess (above 40,000 psi) pressures.

here are some other related "high rail pressure" posts of the past ...

Mark from Canada did it. He was very helpful and also sent me here. I'm really glad there is place like this so we can learn. I also tend to think the worst when something is wrong lol but I'm glad it was a simple fix. 725k no blow by cam looks good and il try to keep it that way ! Mine was done in Dec. 2021 at 515k with my buddy Martin in ca mark did his w900.
