⚠️ Common Signs of Failure

• Diesel weeping or spraying from a union under load
• Misfire or rough running on the cylinder the pipe feeds
• Pipe cracked at a bend or at the union nut collar
• Cone seat on the union damaged, so it will not seal
• Chafe flat where the pipe touches another pipe or bracket

🛠️ Service Notes

• Delivery pipes are cylinder specific — 838874 covers cylinder 2, 838875 cylinder 3 and 838876 cylinder 4, and the weights are within 27 grams of each other, so order by cylinder number
• Never bend a delivery pipe to fit, and do not overtighten the union nuts
• Bleed the fuel system and check every union with the engine running
