Hi, I have a 97 blazer. I replaced the spider assembly years ago and it has ran great till now. I think it might be the fuel pressure regulator. I have the AC delco 89060439 MFI. Has anyone ever replaced just the Fuel pressure regulator in the newer spider assemblies? If i look up the part on a site like Rock Auto for example i dont know if its listing for the old poppet style or the new MFI
Thanks
