I wanted to have an extra set of fuel rails for my 04 5.3. I am going to be switching injectors and driving down to get it tuned, but do not want to foul the plugs during the 40+ mile drive there. If I had an extra set of fuel rails I could switch them in the parking lot in about 10 minutes. Dont know if the 04+ returnless rails are different, or if the return on the early ones is part of the line or rails. If they will work on my 04, I am interested. Shoot me a price shipped to Chicago 60638.

 

I've got a set of 2005 rails and crossover tube. Make me an offer.
