ok so i let my fuel run extremely low the other day and it picked up a bunch of trash out of the bottom of the tank so i changed the fuel filter, got a little better but still not right so i began the task of removing the upper intake to check the injectors, well they were definitely clogged had rust and trash sitting on top of them in the fuel rail. so cleaned the rail and proceeded to remove the injectors to clean them which i have done before when i rebuilt the motor, and the little green seals at the bottom of the injectors are broke on 4 of them my question is are these absolutely necessary and if so does anyone know were i can get just the seals because i definitely dont feel like spending a couple hundred bucks on injectors when all i need is the little green plastic seals that go on the end of the injector where it actually mounts into the engine thanks
