3.0 Fuel Injection 121

We must ensure engine controls move freely and are adjusted per manufacturer instructions. This is crucial for aircraft safety and performance.Lubricate all control rod ends and fuel system components according to TCM Service Bulletin SB95-2 and the Aircraft Maintenance Manual to ensure smooth operation.Locate the IDLE speed stop screw on the throttle body and turn it counter-clockwise two complete turns. For fuel system adjustment, IDLE RPM will be controlled manually.Here we see diagrams of the aneroid and mixture control, along with the throttle and metering assembly, vital for understanding fuel pump turbocharged engines.This diagram illustrates the throttle and control assembly from the front view, essential for GTSiO-520-D, F, H, K, L, M, N engines, showing key components.Here are detailed views of the throttle and control assembly, including a side view for specific engine types, and the fuel pressure regulator for turbocharged engines.We need to inspect the exhaust and induction systems for proper installation, security, and any leaks. Promptly correct any discrepancies found to maintain optimal function.Inspect all lines, hoses, and wire bundles for chafing, loose connections, leaks, or stains. Any detected discrepancies must be corrected to prevent future issues.For turbocharged engines with a fuel pressure regulator, deactivate it during initial fuel system adjustments. Remove the fuel line from the "center" port fitting, referring to Figure 10 for guidance.Install and torque a cap on the "center" port fitting, and a plug on the removed line. Pressure test these areas for fuel leaks before starting any fuel system adjustments.
