(3) Pressure indicator
(4) Pressure tap
(5) Pressure indicator This tool group has an indicator that is used to read the pressure in the fuel manifolds. The Special Instruction, SEHS8907 is with the tool group.Test Preparation - Fuel Manifold Pressure
Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. To help prevent possible injury, turn the start switch off when changing fuel filters or water separator elements. Clean up fuel spills immediately.
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component.
Use a suitable container to catch any fuel that might spill. Clean up any spilled fuel immediately.
