Injector size
 

I need some help. I decided to put a aftermarket intake on my 2006 LQ9 and when I switched manifolds the injectors do not fit in the manifold hole. They are the wrong diameter. I was told to put in LS 2 injectors which is fine but when I try to order I need to reference a car year or other specifics on.

Can anyone help me that have some for sale know what year or size to order.

If you read this and wondered what I was talking about don’t worry it is solved. I got ahold of a local turned who know exactly what I was talking about. He said all I need is to get LS2 Orings and replace the LS1 orings. The two different sizes are .547 and .579.

Problem solved fuel rails in place and ready to set on the 6.0
