ENGINE FUEL INDICATING − GENERAL

1.

General

Engine fuel indicating associated with the engine fuel and control system consists of a fuel
low pressure warning system, a fuel flow indicating system and a fuel temperature indicating
system for each engine. The systems for each engine have like components and are identical
in operation.

Fuel low pressure warning consists of a fuel low pressure switch, sensing fuel pump inlet
pressure and connected by electrical wiring to the caution lights system. Fuel flow indicating
is by means of a transmitter sensing fuel flow to the engine fuel manifold, connected by
electrical wiring to an indicator on the engine instrument panel. Fuel temperature indicating is
by means of a transmitter sensing temperature at the fuel pump inlet, connected by electrical
wiring to an indicator on the engine instrument panel.

For location of the fuel low pressure switches, and fuel flow and fuel temperature transmitter,
refer to ENGINE FUEL AND CONTROL − GENERAL, Figure 1.

Other indications associated with the fuel system are fuel quantity indicating systems, one for
each fuel tank; refer to Chapter 28.
