How do you set timing on a Mack E-7 fuel pump and engine?

To set the timing on a Mack E-7 fuel pump and engine, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder number one. Then, align the timing marks on the fuel pump and the engine's timing gear. Adjust the fuel pump's position as needed to achieve the correct timing, typically indicated by specific marks or a timing tool. Finally, secure the fuel pump and recheck the timing to ensure accuracy.
