and causing leaks.

Installation
・
The Pressure sensor works both from A to B and B to A. Decide the mounting direction according to
your fuselage layout. Apply Hose clamps to both sides of the Pressure sensor.
・
To change the direction of Pressure release valve nipple, loosen the Hexagon head with an 8mm
wrench. Tighten the Hexagon head again after deciding the direction.
・
If there are air bubbles in the tube between the fuel tank and the fuel pressure sensor unit after filling
up the fuel tank, when the ECU switch is turned on for the first time, open the valve until the screw top
becomes flush with edge of the valve holder as shown below. After eliminating the air bubbles, close the
valve. Do not open the valve more than the flush position to avoid the pressurized fuel from coming out
of the valve.
・
Air bubbles beween the Fuel pressure sensor unit and the engine (Injector) are of no concern as they do
no harm since they are discharged through the Injector.
