Condition & Bench Testing

Unlike "pulled" units that may be seized by old fuel residue, this Genuine OEM sender undergoes a strict prep process:

• Internal Cleaning: The protective tube is flushed to remove varnish and sediment.
• Resistance Test: Ohms are verified at "Full," "Half," and "Empty" positions for gauge accuracy.
• Float Integrity: The internal float is inspected to ensure it hasn't become fuel-logged or heavy.

Global Shipping Information

• Secure Handling: These sensors are long and fragile. We ship in reinforced, impact-resistant tubes to prevent bending the internal resistance wires during transit.
