I understand why they have the -10 fitting on them... I was referring to the fact that for our engines, we dont need anything that large....

You can get a -8 or -6 extrusion for the same price as the -10 stuff.... If you look at the top of the injector, it is a very small opening.. now add 5 more injectors. A -6 bore size is plenty big to feed the amount of flow you would need. I have (6) ID1000 (100lb) injectors... I will probably have to sell those and go bigger in the future, as they will be the limiting factor on my fuel system... not the -6 size
