Inspection

INSPECTION

PROCEDURE

1. INSPECT FUEL SENDER GAUGE ASSEMBLY

CAUTION:

Perform the inspection in a well-ventilated area.

Do not perform the inspection near an open flame.

(a) Check that the float moves smoothly between F and E.

(b) Check the fuel sender gauge assembly voltage.

(1) Apply 5 V between terminals 2 and 3.

NOTICE:

  • Be careful when connecting the leads, as the fuel sender gauge assembly may be damaged if the leads are connected to the wrong terminals.
  • Do not apply more than 6 V to terminals 2 or 3.

HINT:

If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series.

F

4.255 to 4.605 V*

Between F and E

0.345 to 4.605 V* (Gradually changes)

E

0.345 to 0.695 V*

*: The output voltage changes depending on the voltage applied to the terminals.

Output voltage (F) = (0.851 x Voltage applied to terminals) to (0.921 x Voltage applied to terminals)

Output voltage (E) = (0.069 x Voltage applied to terminals) to (0.139 x Voltage applied to terminals)

If the result is not as specified, replace the fuel sender gauge assembly.

Installation

INSTALLATION

PROCEDURE

1. INSTALL FUEL SENDER GAUGE ASSEMBLY

(a) Engage the claw to install the fuel sender gauge assembly to the fuel suction tube with pump and gauge assembly.

NOTICE:

Be careful not to bend the arm of the fuel sender gauge assembly.

(b) Engage the 2 clamps to connect the wire harness to the fuel suction plate sub-assembly.

NOTICE:

Do not damage the wire harness.

(c) Connect the fuel sender gauge assembly connector.
