I think I have leaky o-rings. After installing a new lower intake I have a fuel problem the fuel is leaking and losing pressure. I was just wondering what all I need to replace the O-rings. I beleive I just need 8 Injector O-rings and an upper intake manifold gasket set right?? If not tell me what I need. Thanks guys. Its on a 1992 5.0L EFI

None of those say how to install the injectors. They all just say to put it back together

I used a little smear of Vaseline all the way around my o rings the one time I installed injectors...
