Installation notes
Secure the cup with the supplied clamps to the underside of the air filter housing. Fill with engine oil up to the pressed fill-line marking — do not overfill to prevent oil draw into the carburettor. Preferably use SAE 30 engine oil or the same viscosity as in the engine.
Compatibility
Fits standard oil bath air filters with clamp fastening. Note: some cups have an inner cup with openings — verify that dimensions (approx. 6¼" internal diameter) match your existing housing.
Historical context
The oil bath air filter system was standard fitment on military jeeps and light trucks until the early 1960s. The oil-filled cup acted as the first filter stage where dust settled in the oil, after which air flowed through a metal mesh element.
