hey, I have a 97 xlt with a 2.3 eng. It is bad. I also have a 99 with a 2.5 I want to replace the 2.3 with the 2.5 I noticed the 2.3 has two fuel lines going to the fuel rail and t he 2.5 only has one. Is this exchange possible? If so what do I do with the other fuel line? Thanks for any help you can give. Also I am planning on leaving the eng. wiring harness with each eng. and just unplug the multi pin connector will that work?
