I am thinking about replacing my fuel injectors, and have never done it before. For people whom have replaced them on the 2000 5.3L vortec, I have a few questions....

  • Delco or not?
  • If not, what brands are good? what brands to avoid?
  • Do I need anything else? ( I see all these gasket kits( o-rings)) that are sold seperately.
  • Should I take a little fuel and coat the o-rings ( like we do with our oil filters and a little bit of oil) before installing them
  • Anything else that might be helpful also.
