Diagnosing Low Fuel Pressure on My PACCAR MX-13 (Step by Step)

My 2019 Kenworth T680 with a PACCAR MX-13 started throwing low fuel pressure codes, an orange wrench light, and even went into a torque derate. Before spending thousands replacing parts, I decided to diagnose the problem myself. In this video I walk you through the entire process, including: • Reading the fault codes • Checking fuel pressure with my scan tool • Replacing both fuel filters • Comparing the old filters to the new ones • Testing fuel pressure after the repair • Seeing if the derate and low fuel pressure issue improved If you own a Kenworth, Peterbilt, or any truck with a PACCAR MX-13, hopefully this video helps you diagnose your truck before throwing expensive parts at it.
