How often should FP samples be taken?

The correct approach to sampling fuel pressure (FP) is to take a sample 5 minutes after the system starts, followed by additional samples taken every 30 minutes thereafter. This procedure is critical because it ensures that initial readings are captured when the system is still stabilizing, allowing technicians to monitor changes in performance as various systems come online and operate under load. Sampling too frequently or at inconsistent intervals might yield data that is less reliable, especially if the system experiences fluctuations just after startup. Therefore, the proper timing of the first sample helps establish a baseline under stabilized operational conditions, while subsequent samples at regular intervals every 30 minutes provide continuous monitoring that is crucial for maintaining system integrity and performance.
