Looking at the parts books, I see two different rails listed for 07 L61s. These different rails list different fuel injectors. Does any one know if the rails are interchangeable? Here is a picture showing both rails. Does anyone know the differences in the injectors and the differences in the rails?
I could be wrong but i believe the top rail is for a returnless fuel system?
They are both returnless. All of the new L61s are returnless fuel systems. The lower one is not the one from the 03-05 Cavi. Its from the Cobalts.
Weird... could be a make to make difference GM has used the l61 on several platforms globally. That's all I can guess.
looks like the top one has dampener on it the other doesnt

What I keep running across is that the top one might be from the LE5 and the bottom from the 2005+ L61. Can anyone confirm this?
Probably have better luck on a Cobalt site to be honest.
