Either too much fuel or not enough fuel for combustion can be the cause of a problem in the fuel system.Many times work is done on the fuel system when the problem is really with some other part of the engine. The source of the problem is difficult to find, especially when smoke comes from the exhaust. Smoke that comes from the exhaust can be caused by a bad fuel injection nozzle, but it can also be caused by one or more of the reasons that follow: a. Not enough air for good combustion.b. An overload at high altitude.c. Oil leakage into combustion chamber.d. Not enough compression.e. Fuel injection timing retarded.Fuel System Inspection
A problem with the components that send fuel to the engine can cause low fuel pressure. This can decrease engine performance. 1. Check the fuel level in the fuel tank. Look at the cap for the fuel tank to make sure the vent is not filled with dirt.2. Check the fuel lines for fuel leakage. Be sure the fuel supply line does not have a restriction or a bad bend.3. Install a new fuel filter. Clean the primary fuel filter, if so equipped.4. To remove air from the fuel system, use one of the procedures that follow for the correct application:PC Engines:
(a) Use the priming pump to remove air from the low pressure side of the fuel system.(b) Loosen (one at a time) the fuel injection line nut one-half turn at the valve cover base adapter. Use the priming pump until fuel without air flows from the loose connections, then tighten the nut. Repeat the procedure for each fuel injection line.DI Engines:
(a) Use the priming pump to remove air from the low pressure side of the fuel system.(b) Loosen one-half turn the fuel injection line nuts at the adapter in the valve cover base. Use the starter motor to turn the engine until fuel without air flows from the loose connections. Tighten the nuts. Because of the check assemblies in the injection pump outlets for the DI engine, the priming pump will not give enough pressure to remove air from the fuel injection lines.5. Inspect the bypass valve in the fuel transfer pump to see that there is no restriction to good operation.Engine Cylinders Checked Separately
An easy check can be made to find the cylinder that runs rough (misfires) and causes black smoke to come out of the exhaust pipe.Run the engine at the speed that is the roughest. Loosen the fuel line nut at the adapter in the valve cover base. This will stop the flow of fuel to that cylinder. Do this for each cylinder until a loosened fuel line is found that makes no difference in engine performance. Be sure to tighten each fuel line nut after the test before the nex fuel line nut is loosened. Check each cylinder by this method. When a cylinder is found where the loosened fuel line nut does not make a difference in engine performance, test the injection pump and nozzle for that cylinder.Temperature of an exhaust manifold port, when the engine runs at low idle speed, can also be an indication of the condition of a fuel injection nozzle. Low temperature at an exhaust manifold port is an indication of no fuel to the cylinder. This can possibly be an ind
