Re: 2000 gmc 2.2 flex fuel engine swap
The Flex injectors are different. Keep your manifold and fuel rail to work with the flex system. Also, at some point, they did away with the EGR valve system not exactly sure when. If the new one has the EGR, discard that and use your old block off plate on the back of the head. Use your exhaust manifold and gasket to work with your truck's AIR system.
Not sure how this got in the Flame section.
