Timing #1 Cylinder to fuel pump

How do I set the #1 piston in the proper position to remove the American Bosch fuel pump so I can have it rebuilt? This is on a 1961 Mack B61 with END 673 engine that has been idle for about 30 years. Engine starts with starter fluid, but I am not getting fuel out of the fuel pump. How do I determine TDC for #1 and where do I need to have the piston for the fuel pump to be reinstalled to start the fuel feed to #1?.
