So on Tuesday the fuel rail I ordered (12621662) was delivered. It did not work. After deeper research I found the correct fuel rail. If you want to use the fuel injectors (OEM 2002 Tahoe Flex Fuel - my Tahoe) which I do, then this is the wrong fuel rail. The correct fuel rail for my application is 12660709. It was delivered today and I verified the fit with a spare flex fuel injector I had on hand.
Below is the picture of the fuel rail and then the fuel rail on the manifold. The red circle is where the two fuel rails are different. The correct one for my build the keeper for the top part of the injector is a little bit longer to accommodate the OEM flex fuel injectors.
