Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
Certain F2 series machines installed with Tier II or Tier III engines have reported low power from the engine. After troubleshooting, this low power has been diagnosed as being a faulty fuel injection pump.

Before replacing the fuel injection pump, the following actions can be performed to help ensure that the low-pressure fuel system is in good condition.
There is fuel in the fuel tank
Inspect the fuel filter for excess contamination, if necessary, install a new fuel filter
Check the fuel strainer in the bottom of the fuel tank is not blocked or damaged
Check that the fuel lift pump is delivering fuel to the fuel injection pump.
Check that the fuel tank has been regularly drained of any water contamination, and is clear of any debris that could be restricting the fuel flow. See the Operation and Maintenance Manual for correct maintenance practices.All these issues can cause low fuel pressure problems that could lead to thinking the fuel injection pump is faulty. If the low-pressure fuel system is working correctly, then inspect the fuel injection pump for water damage. Refer to special instruction REHS3767. If the fuel injection pump contains rust, then the root cause of the problem is water in the fuel supply.If necessary, a replacement fuel injection pump may be obtained. Refer to disassembly and assembly, "Fuel Injection Pump - Install" for the correct procedure to install a replacement fuel injection pump.Ensure that the fuel supply is clean and the fuel tank does not contain any water or contamination before installing a new Fuel Injection Pump. Also, replace the fuel filter. If a failure occurs, report the failure to the product group by completing a CPI Feedback Form at the Service Information Management System (SIMSi). Reference CPI 373959 and TIB , M0082583 in the form. The link to SIMSi can be found on the Caterpillar Service Information System (SIS).Note: For machines equipped with 501-4461 Fuel Priming Pump and Primary Filter Gp which has an extra water separation volume. Itis recommended to remove any aftermarket water separator.
