Briggs & Stratton 01897-0 - Manual (Page 13)

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.
NOTE: A digital manometer, P/N 19495, is available at your
local Briggs and Stratton Power Products service center.
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.
