1. Remove fuel gauge sender from fuel tank.
2. Connect Rotunda 73 digital multimeter 005-00051, or equivalent, to fuel tank sending unit "Y" and "BK/GN" wire terminals.
3. Adjust float rod to empty stop position closest to filter. Resistance should be 14-18 ohms.
4. Adjust float rod to full stop position. Resistance should be 155-165 ohms.
5. Slowly move float rod from empty to full stop position. Resistance should increase slowly.
6. If sending unit does not operate as specified, replace it. If unit operates as specified, refer to pinpoint test. Pinpoint Tests
