The manometer port permits temporary installation of a
manometer (Figure 5), to ensure that the engine receives
the correct fuel pressure to operate efficiently throughout
its operating range.

When the initial test runs are completed, the manometer is
removed and the port is plugged.A typical final fuel
connection assembly is shown in Figure 6.
