Safety Precautions: Work in a well-ventilated area away from open flames or sparks. Wear safety glasses and fuel-resistant gloves. Keep a fire extinguisher nearby.
Tools Needed: Fuel pressure gauge (0–30 psi range), T-fitting, fuel-rated hose clamps, box-end wrenches, and a drain pan.
Steps:
- Place a drain pan under the rear in-line fuel filter and the main canister filter to catch residual fuel.
- Disconnect the fuel line between the electric pump and the main canister filter. Install a T-fitting with a fuel pressure gauge to monitor the pressure at this junction.
- Inspect the rear in-line filter. If debris is visible or the filter is aged, replace it with an OEM-equivalent unit.
- Inspect the main canister filter element. If clogged, replace the filter element following the specific Alfa Romeo service manual procedure for the SPICA canister.
- Activate the electric fuel pump (without starting the engine) and check the gauge reading. If the pressure is below 10 psi, replace the electric fuel supply pump.
- Once the new components are installed and the gauge shows a steady 10–20 psi, remove the T-fitting and reconnect the fuel lines securely.
- Start the engine and verify that the fuel system maintains pressure and the engine holds an idle without stalling.
