Technical Is My Fiat 124 Fuel Injected?

[stevenk9958]

How do I know if my 1978 Fiat 124 with the 1.8L I4 engine is fuel injected? I have a gasoline vapor filter, is that related to whether or not the engine is fuel injected?

I'm fairly sure the presence of a gasoline vapor filter has no bearing on fuel injection or not.

To ascertain fuel injection vs carburetor you have to look at the inlet manifold and any engine control unit.

It should be immediately obvious under the bonnet, carb or fuel rail to injectors.

A pic of the engine bay would help

Well not always. Early electronic fuel injection system used single point injection with carburetor type looking bodies and no fuel rails. I can tell but less knowledgeable persons may not be able to.

Yes pictures say a 1000 words.

If the car is fuel injected, which I doubt, then it is most probably a Fiat/Marelli/Weber system. Fiat/they started experimenting with fuel injection in 1972 with details released in 1977. I don't think real use of the system in vehicles started till after 1980.

The 124 Spider didn't get fuel injection (Bosch L Jetronic) until 1981 on the 2 litre engine. Previously all the engines used (1.4 - 2.0 litre) had carburettors.
