Fuel System, Tanks & Carburetors for Jeep CJ3B
Carburetor, Sending Unit, Fuel Tank & Pump for Reliable Fuel Delivery (1953–1964).
Why the Willys CJ3B Fuel System Needs Attention After Decades of Use.
The fuel system of the Willys CJ3B combines several components that work together to deliver a clean fuel mixture and reliable supply to the 4-134 Hurricane engine – and after decades in service, each of them shows its own wear. The gasket between the carburetor and intake manifold hardens and becomes porous over time, letting in false air that causes a rough idle or hard starting. Inside the carburetor itself, the float, jets, and gaskets wear down, leading to an uneven idle or increased fuel consumption. The fuel sending unit corrodes from constant contact with fuel and moisture and then delivers inaccurate level readings, while the filler neck gasket dries out and starts to leak. The mechanical fuel pump wears from the constant diaphragm motion, and even the steel tank can lose its seal over time due to rust and sediment build-up.
- Carburetor & Carburetor Parts: The carburetor base gasket seals the transition to the intake manifold, the Weber Performance carburetor kit fully replaces the original Carter carburetor, and the carburetor repair kit renews wear parts in the existing 1-BBL carburetor.
- Sending Units: The sending unit for 5-bolt mount models and the sending unit for 6-bolt mount models provide reliable fuel level signals for 6- or 12-volt electrical systems.
- Fuel Tank & Filler Neck: The filler neck gasket and the complete 40-liter steel fuel tank ensure a tight fuel supply.
- Fuel Pump & Gasket: The fuel pump gasket and the mechanical fuel pump with glass bowl reliably deliver fuel to the carburetor.
