The May 26, 1980 Service Magazine article, "New Check Valve Used In Fuel Injection Pump Assembly," and the June 2, 1980 Service Magazine article, "Reverse Flow Check Assembly Now Used In Fuel Injection Pump Assemblies," told of two new check valves used in 3208 Industrial Engines.
The 8N1414 Fuel Injection Pump Check Assembly (reverse flow check) is used in 3208 Industrial Engines, Serial Numbers 90N37285-Up, with engine arrangement numbers 8N4537, 8N4538, 8N4539, 8N4540, 8N4541, 8N4542, 8N4543, 8N4544 or 8N4545.
