I used it when I switched mine out for modded ones. The GBODs suck. I did put them back because I thought they actually serve a purpose. Make sure you have new gaskets and that you don't pinch one. My first system pressure up I had an arc of gas about a foot and a half tall shoot out of the car.
so just the GBOD's gaskets and new top and bottom o-rings for the injectors are the gaskets I should need?
Just the injector o rings. The GBOD just hold the injectors and fuel line in place - no gaskets that I recall.
