Gas Tank Sending Unit 6 or 12-Volt; 46-53 Jeep

The Gas Tank Sending Unit for 6 or 12-Volt systems, compatible with 1946–1953 Jeep models, is an essential fuel system component for classic Jeep restoration and daily operation. Whether you're rebuilding a CJ-2A, CJ-3A, or Willys MB, this OEM-specification sending unit provides accurate fuel level measurement to your gauge cluster. Vintage Jeep fuel systems rely on a functioning sender to display real-time tank capacity, preventing unexpected fuel starvation on trail runs or highway drives.

The sending unit operates on either 6-volt or 12-volt electrical systems—a critical compatibility feature given that many early Jeeps were originally 6-volt equipped, while restoration builds often upgrade to 12-volt alternators and wiring. Inside the tank, a variable resistor attached to a float arm changes resistance as fuel level drops, translating that mechanical motion into accurate gauge needle movement on the dashboard. This OMIX-ADA unit maintains stock specifications and dimensions, ensuring seamless installation into the factory fuel tank opening without requiring tank modification or custom fabrication.

Restoration enthusiasts, weekend warriors, and Jeep collectors benefit from this reliable replacement when original senders fail or corrode—a common issue in tanks exposed to moisture and ethanol fuels. Installation is straightforward: drop the unit into the tank opening, secure the locking ring, and reconnect the single wire lead to your gauge circuit. Compact dimensions (3.7 × 3.65 × 9.4 inches) and lightweight construction (0.44 lbs) confirm this is an exact fit for 1946–1953 Jeep fuel tanks, restoring fuel gauge accuracy for safe operation.
