B. Viewing the timing line on the pump-cam through the timing window, rotate the pump in normal direction of rotation (with pressurized air line hooked up).
C. When resistance is felt, the cam rollers inside the pump are just contacting the cam (getting ready to inject).
D. At this point, the two timing lines in the pump window should be in line. If not, one is incorrect.
