[98SteedaGT]

I thought the returnless fuel system was introduced in 99. I noticed on my fuel rails when I changed out my intake that I have two fuel lines connecting to the passenger side fuel rail, then of course the front and rear tips of the rails have cross overs to feed the other side. I also noticed that I have a large cylindrical device where one of the fuel lines meets on the rail, it has what appears to be some sort of screw in the middle and a vaccuum port on the side. I also see what appears to be a directional check valve on the other line. I am not saying that I am disagreeing with you, I am just curious as to why I have two lines coming in to the system on one side. Any ideas, I am still not totally used to my GT yet...
