Fuel System Parts for Willys M38
Carburetor, Tank & Cables for Reliable Fuel Delivery (1950–1952).
Why the Fuel System in the Willys M38 Needs Attention After Decades.
The fuel system of the Willys M38 is one of the most vulnerable areas on the vehicle after more than 70 years. The carburetor and its intake horn sit directly above the hot L-head engine, causing gaskets and rubber connections to harden, crack, and draw false air over time. The steel tank mounted under the seat corrodes from the inside due to condensation and old fuel, leading to rust, leaks, or a failed sending unit. Throttle and choke cables wear mechanically, their housings crack, and the cables begin to stick or become hard to operate. The fuel pump gasket also hardens and starts leaking, resulting in irregular fuel flow or a loss of power. Anyone looking to keep their M38 roadworthy or restore it to original spec should check the entire fuel system regularly for leaks and proper function.
- Carburetor & Intake Horn: The carburetor air horn set or the individual carburetor air horn, plus the matching carburetor to manifold gasket for a tight seal on the L-head engine.
- Fuel Tank & Sender: The complete steel gas tank, the matching fuel sender unit, and the gas tank filler neck grommet for the side-mounted filler.
- Control Cables: Accelerator cable with knob and choke cable with knob in original olive-drab styling.
- Fuel Pump: The fuel pump gasket ensures a tight seal for the mechanical fuel pump connection.
