I have a 1999 ETC and the nylon fuel rail was leaking, so I ordered a stainless steel fuel rail. I also noticed there was two part numbers for the fuel pressure regulator, one for the nylon and one for the stainless rail.
Can I use my old FPR on my new stainless rail?
When ordering a new FPR for my '96 caddy, I remember seeing the option for stainless steel fuel rail or original nylon fuel rail. So you might want to get the FPR that is recommended for the stainless steel fuel rail.
the AC-Delco nylon fuel rail FPR for $37.79 (part # 2171598) and the stainless steel fuel rail FPR for $41.79 (part # 2171630).
