This guide is intended to aid the owner-mechanic in understanding and diagnosing Alfa Romeo SPICA fuel supply system
malfunctions. It is not a substitute for the official factory repair publications. No claim to absolute accuracy or utility is
expressed or implied. The reader uses this guide at his own risk.

As an early caveat, keep in mind that Alfa Romeo did not necessarily change the specifications and equipment design in strict accordance with model years. It is possible to have cars of the same model year with components from different manufacturers or systems that are slightly different from one another. In the following descriptions, references are made to model years, but you must look at your particular car to determine the exact system design and component installed. In addition, previous owners (PO’s) may have substituted components from other model years.

Something else to consider is your own ability and knowledge. This guide assumes the reader has a basic knowledge of automotive systems, experience in mechanical repairs, and safety practices.

The fuel supply of the SPICA Fuel Injection System has traditionally proven to be the most troublesome part of the system. Specifically, the most common failures are: 1) Clogging of the rear in-line fuel filter. 2) Weak or failed fuel supply pumps. 3) Rusted, leaky, and dirty fuel tanks (that clog rear fuel filters).
