All,
Had a diesel engine which indicated high fuel rail pressure.
With another pressure gauge, it was indeed too high.
The return line to the tank was suspect. Two lines combined into one at a tee. I had a 50/50 chance of getting it right.
Here's the good part, the fuel tank was plenty cold, and just by feeling the fuel lines (engine running) with my hands, could tell which was the culprit, and where the obstruction was.
Made for a simple repair. Break the line and find the faulty check valve innards.
Good thing Minnesota is cold !
