7.

Disconnect harness connector (A) and quick connector (B).

• Remove quick connector in the following procedures.
- Pinch quick connector square-part (A) with your fingers, and

pull out the quick connector by hand. 

- If quick connector and tube on sender unit are stuck, push and

pull several times until they move, and pull out.

CAUTION:

• Quick connector can be removed when the tabs are

completely depressed. Never twist it more than neces-
sary.

• Never use any tools to disconnect quick connector.
• Keep resin tube away from heat. Be especially careful

when welding near the resin tube.

• Prevent acid liquid such as battery electrolyte, etc. from

getting on resin tube.

• Never bend or twist resin tube during installation and disconnection. 
• To keep the connecting portion clean and to avoid dam-

age and foreign materials, cover them completely with
plastic bags or something similar.
