FUEL TANKS
The airplane has two fuel tanks, one in each wing. The fuel flows from
the wing tip to the wing root by gravity. A collector box in the wing root
keeps the electrical pumps inlets submerged. To prevent pumps
cavitation, a ejector pump and flaps valves ensure enough fuel in the
collector box at all conditions.
The fuel tank capacity changes according to airplane model. The
EMB
-145LR/LU and EMB-135LR models are equipped with a wing
stub tank that increases the tank capacity. These airplanes have the
collector boxes located in the wing stub.

When performing pressure refueling, the usable fuel quantity in each
tank may be reduced by 7.9 US Gal (STD, ER and MP models) or
13.2 US Gal (LR model) maximum.
NOTE:
When operating with the TS-1 fuel, the FQIS may display a
fuel quantity 2% (two percent) higher than the actual fuel
loaded in the airplane.

FUEL TANK VENT SYSTEM
The purpose of the fuel vent system is to prevent damage to the wings
due to excessive buildup of positive or negative pressures inside the
fuel tanks. The system consists of float vent valves, vent lines, a surge
box and a NACA air intake. The surge box is located in the wing and it
is connected to the fuel tank through two float valves. These valves
allow at least one venting point to be open between the surge box and
the fuel tank under any flight condition. The surge boxes are
connected to outside air through a NACA air intake installed under the
wing.
