Disconnect the fuel hose from the fuel delivery pipe of the throttle chamber,
then install a suitable fuel gauge.
NOTE: Before disconnecting the fuel hose, disconnect the
fuel pump connector and crank the engine for approximately 5 seconds to
release the pressure in the fuel system. If the engine starts, let it run
until it stops.
Measure fuel pressure with the engine idling. The fuel gauge should read
20–24 psi (136–163 kPa). If not within specification, replace
the pressure regulator.
