'98 is nylon but steel won't hurt...
Go to a junk yard and look for '95-'97 Seville/Deville/Eldorado. They should all have steel line (assuming the owners had the recall done). It is a far better fuel lime than the nylon one. Under no circumstance use a nylon line of a '95-'97 car, if you don't like the metal one then use '98-'99 nylon fuel line.

Ok, I have the new steel fuel rail. It is set up different than the nylon one. I just need to know exactly how to make the transition from nylon to steel. Do I need new fuel lines? I read the nylon or steel fuel rail forum and just need to make sure I do this right. Thanks for all the info.

Ok. I was just reading in the thread (nylon or steal fuel rail?) posts 9,14,16,18 and 21, talks about some adjustments that had to do with changing fuel rails. I am just trying to figure out if those post will involve me and what I am trying to do. I have both fuel rails in the picture provided in thread.

Not sure what thread you are talking about, but the stainless steel fuel rails where made as a direct replacement for the recalled rails. Dealers where swapping them out in 30 minutes or less. They should be plug and play.

Time for a update. New parts. Water pump cam tensioner and belt, Front engine mount, PCM, fuel rail, injectors, fuel pressure regulator, serpentine belt, top radiator hose, oil pressure sensor, acdelco plugs and wires. Am hoping this solves my cold start and rough idle problems. I cleaned the tb. I would appreciate any feedback or thoughts.
