Alfa Romeo 105 Fuel System Spare Parts for Classic Alfa Romeo Models

The fuel system of the Alfa Romeo 105 series supplies the Twin Cam engine and is used in the Giulia, Berlina, GT Bertone and Spider 105/115. It includes the tank, fuel pump, lines, carburettor, flanges, seals, filters and tank sender. As a manufacturer, supplier and spare parts specialist for classic Alfa Romeo models, Alfa-Service carries a wide range of fuel system parts. Many components are comparable across the series, while the tank and line routing can be model-specific and the carburettor set-up differs by engine.

Alfa Romeo 105 Fuel System at a Glance

The fuel is stored in the tank, routed via lines to the fuel pump and from there to the mixture preparation. On most cars the mixture preparation is via carburettors, while certain late versions use fuel injection. The tank sender reports the fuel level, flanges and seals provide tight connections, and filters hold back contaminants. The basic function is the same across the series, but the version of the tank, lines and carburettor set-up depends on model and engine.

Fuel System Part Types

The range is divided into the following part types:

Tank and tank accessories
Fuel pump, mechanical or electric on injection cars
Fuel lines and connections
Carburettor and carburettor parts
Flanges and seals
Fuel filters and gauzes
Tank sender

Shared Across the Series or Model-Dependent

The carburettor and fuel pump are often comparable across the series, since they are closely linked to the engine. The tank and line routing, by contrast, are model-specific, because the body and routing differ between coupe, saloon and Spider. The carburettor set-up depends on the engine: cars with twin carburettors, an early single carburettor or injection differ in carburettor parts, flanges and connections. For the fuel pump, it should be noted that carburettor cars mostly use a mechanical, engine-driven pump, while injection cars can have an electric delivery. The Giulia, Berlina, GT Bertone and Spider 105/115 thus share engine-near components, while the tank, lines and tank sender are to be chosen by model and model year.

In practice it is helpful to separate engine-near and vehicle-side parts. The carburettor, pump and associated seals depend on the engine variant, while the tank, lines and tank sender are selected by model and body. Fuel filters and gauzes are chosen to match the supply path. Comparing with the existing system on the vehicle, in particular the line routing and carburettor set-up, prevents wrong purchases.

Notes on Part Selection

Decisive are the model, model year and engine as well as the carburettor or injection set-up. The tank and line routing are to be chosen model-specifically, the carburettor and pump by engine variant. The tank sender must match the display and the tank opening. Anyone who first establishes the model and engine variant and checks the existing line routing can put together the tank, pump, lines, carburettor, filters and tank sender reliably.

In the interplay, the fuel system carries the fuel from the tank via lines and pump to the mixture preparation. The tank stores the fuel and holds the tank sender, which reports the fuel level to the display. The fuel pump delivers the fuel to the carburettor or injection, while lines, flanges and seals form the connections. On most cars the carburettor prepares the mixture, and fuel filters and gauzes hold back contaminants. Many of these parts are regularly requested maintenance and renewal items. For assignment, a distinction should be made between engine-near and vehicle-side parts.

The carburettor and fuel pump depend on the engine: cars with two twin-choke carburettors, an early single carburettor or injection differ in carburettor parts, flanges and connections, and the fuel pump is mostly mechanical on carburettor cars and partly electric on injection cars. The tank and line routing, by contrast, are model-specific, since the body and installation position differ between coupe, saloon and Spider. The tank sender must match the display and the tank opening. This separation makes selection considerably easier, because engine-near parts can be determined via the engine variant and vehicle-side parts via the model.

In practice it is advisable to view the system from the tank to the mixture preparation and to choose the carburettor, pump and seals by engine variant, the tank, lines and tank sender by model. Fuel filters and gauzes are added to match the supply path. Comparing with the existing line routing and carburettor set-up on the vehicle prevents wrong purchases. The Giulia, Berlina, GT Bertone and Spider 105/115 share the engine-near components, while the tank, lines and tank sender are selected model-specifically.

As a manufacturer, supplier and spare parts specialist for classic Alfa Romeo models, Alfa-Service assigns the fuel system parts clearly by assembly and model family. The range covers the whole 105 series, so that the tank, fuel pump, lines, carburettor, flanges, seals, filters and tank sender for the Giulia, Berlina, GT Bertone and Spider 105/115 can be found reliably. Engine-near parts such as the carburettor and pump can be determined via the engine variant, while the tank, lines and tank sender are narrowed down via the model. This separation makes selection easier, because the two areas can be assigned independently of one another.
