Nothing like that on any of my old Alfas. Lol, my old Sprint GT had one of the glass bowl sediment filters in line. Thought it was funny looking. Have to admit, don't know if it was OEM or Carlo added it later. He did add cool looking clear green plastic fuel line between the engine mounted fuel pump and the carbs above, which turned out to be a disaster, getting brittle with age and cracking, spraying gas on the distributor. To this day, don't know why the car didn't go up in flames.
