06 Heritage Classic
What year did Harley stop using Magneti-Marelli Fuel Injection and go to Delphi FI? I'm going to look at a 2006 Heritage Classic and want to insure it does not have the MM FI. Are there any visual tell-tale signs?
TIA for any help.

Softails never had the MM EFI, that was only on Touring bikes.
All softails started EFI with the Delphi EFI unit in 2001.... Touring models went to Delphi EFI in 2002....
That bike will have a Delphi EFI, or a carb. The quick tell is that if it's got a carb, it has a fuel tank petcock. The EFI just has the fuel line connector at the tank, no petcock.
Since you asked, the MM EFI can be spotted by the two fuel lines.... High pressure supply line & low pressure return line.. and of course the dual butterfly throttle body.
