Sub Sending Unit
Remove sub fuel gauge sending unit. Measure resistance between terminals No. 1 and 2 at fuel gauge sending unit while moving float up and down. See Fig 2. Resistance should increase as float is lowered. See SUB FUEL GAUGE SENDING UNIT RESISTANCE table. Replace if necessary.
MAIN FUEL GAUGE SENDING UNIT RESISTANCE
| Float Position | Distance From Sending Unit Base - In. (mm) | Ohms |
|---|---|---|
| "F" | 1.244-1.480 (31.6-37.6) | 1.0-3.0 |
| 1/2 | 1.945-2.181 (49.4-55.4) | 23.1-29.1 |
| "E" | 5.193-5.429 (131.9-137.9) | 47.7-49.7 |
SUB FUEL GAUGE SENDING UNIT RESISTANCE
| Float Position | Distance From Sending Unit Base - In. (mm) | Ohms |
|---|---|---|
| "F" | .256-.492 (6.5-12.5) | 1.0-3.0 |
| 1/2 | 4.232-4.468 (107.5-113.5) | 30.0-36.0 |
| "E" | 8.012-8.248 (203.5-209.5) | 60.3-62.3 |
