I just want to say this must be a dumb question, but please lets keep this short and sweet. I picked up another 2.4 today. The engine I think came out of a Grand Am or something else, but I know it is an 01 engine. It has a different style fuel lines with a big circle thing in the middle of the line before it goes into the rail. What is this, and should I just swap out my lines instead since I just unbolted them and keep them attached? Thanks...

Other then leaving my new plugs and some other small things in the back seat of the truck I rented my weekend was great.

I guess I will just buy them again and return the others when I get them Saturday cause they are closed tomorrow.

I used to race cars, now I race myself.

I do not know exactly what is is, but have seen them on Grand am's and Alero's. I would use the rail and lines that is in your car, not what is on the engine.

Checkvalve..........you dont need it, but thats what it is.
That was on my lines when I bought my engine. Just swap em out.
