OE: 77363652 Fuel Filter for Fiat Palio | Fiat

The OE: 77363652 fuel filter is designed for the Fiat Palio, a compact hatchback widely used in South America, India, Africa, and other emerging markets.
Its FIRE-series gasoline engines—1.0L, 1.2L, and 1.6L—depend on clean and steady fuel flow to maintain efficient combustion. This filter prevents contaminants from entering the injection system, supporting smooth acceleration, stable idling, and long-term engine durability across varied driving environments.

Compatibility

This fuel filter fits Fiat Palio (1999–2017) equipped with FIRE gasoline engines, including:

• 1.0 FIRE

• 1.2 FIRE

• 1.6 16V FIRE

Because multiple Palio generations share the same fuel-system structure, workshops can simplify their inventory by using this filter across several market variations. This OE fuel filter is used across Fiat small-car platforms, including Palio and sedan derivatives such as Siena.
It performs reliably in regions with inconsistent fuel quality, a common scenario for many Palio ownership markets.

Filtration / Material / Mechanical Design

The filter uses a synthetic multi-layer medium engineered to capture fine impurities without restricting fuel flow.
A reinforced steel housing withstands temperature and pressure fluctuations typical of compact gasoline engines.
Internal components resist corrosion caused by local fuel additives and moisture exposure.
OE-specific inlet and outlet connections ensure precise installation and stable sealing, reducing the risk of pressure drops that could affect throttle response.
This design helps maintain consistent injector spray patterns, improving combustion efficiency across all FIRE engine variants.

Flow Stability & Engine Protection

Clean and stable fuel delivery is essential for the Palio’s high-revving FIRE engines.
This filter supports smooth engine response during both urban traffic and highway speeds.
Reliable filtration reduces the buildup of deposits on injectors, improving fuel economy and extending injector life.
Consistent flow also contributes to dependable cold starts and minimizes stress on the fuel pump during frequent stop-and-go usage.
