About Installation and Operation(for customer and installation personnel)

1) The rubber hose attached to the sensor should be as short as possible. Attach the sensor with bolts(M6) in the engine compartment in an area where it will not be subject to excess heat or vibration.
2) Access to the air pressure intake may be obtained between the surge tank and the fuel regulator.
(A)Detach the vacuum hose from the surge tank side that has less pressure oscillations and connect
it to the point (a) or (b) of the three way joint.
(B)In order to connect the surge tank with three way joint, cut the required length of the hose fromthe included rubber hose.
(C)Use the remaining rubber hose to connect the sensor to the three way joint.

Warning
To avoid disconnection of rubber hose and air leak, attach hose clamps or use tie-wraps to secure theadjacent hose in the engine compartment. Disconnected hose or air leak could cause damage to the engine.

Confirmation
The length of the included rubber hose is 0.5m. Please adjust appropriately.
The included three-way joint can be used only for the piping inner diameter of Φ 4 between the surge
tank and fuel pressure regulator. In case of other than Φ4, use another joint that fits properly.
The sensor must be installed being the rubber hose connection side faced down.
For vehicles which have a solenoid valve between the surge tank and the fuel pressure regulator,
place a three-way joint closer to the surge tank side than to the solenoid side.
