Fuel Crossfeed (One-Engine-Inoperative Only); Engine Driven Fuel Pumps; Fuel Boost Pumps; Lo Position - Beechcraft Baron G58 Pilot Operating Handbook

Section 7
Systems Description
FUEL CROSSFEED (ONE-ENGINE-INOPERATIVE
ONLY)
The fuel lines for the engines are interconnected by crossfeed
lines. During normal operation each engine uses its own fuel
pumps to draw fuel from its respective wing fuel system. How-
ever, on emergency crossfeed operations either engine can
consume the available fuel from the opposite side.
Position selectors in detents only. There is
no fuel flow to the engines between detents
(indicated by red arcs). Visually confirm fuel
selector position.
The fuel crossfeed system is provided for use during emer-
gency conditions. The system cannot transfer fuel from one
wing system to the other. The procedure for using the cross-
feed system is described in Section 3, EMERGENCY PROCE-
DURES.

ENGINE DRIVEN FUEL PUMPS

The IO-550-C engines are equipped with engine driven fuel
pumps that require manual leaning.

FUEL BOOST PUMPS

The fuel boost pumps are dual-speed, dual-pressure, electri-
cally-driven, vane-type pumps. HI pressure, LO pressure or
OFF is selected with each fuel boost pump switch on the pilot's
subpanel. The LO position may be used to supply a low boost
to the fuel flow during all flight conditions when required. The
pumps are used to perform the following functions:

LO POSITION

1. Minor vapor purging
2. Increasing fuel flow
3. Crossfeeding fuel for One-Engine-Inoperative Operation
4. In-Flight air starts
