Problems with the 2004 730LD diesel

[RobertM02]

I purchased a 2004 730LD with a diesel leak. To make a long story short, the pipes were reversed at the point where they came from the tank. I installed new injectors and return pipes, and the fluid still hasn't made it to the injectors. Error codes 004020, 0046D1, and 004B90 are all present. I am requesting your assistance.

Not everyone checks this area just to say hello, so it might be best to ask in the appropriate place.

Please tell me where I should post this; I appreciate your response.
