Thanks for all the Help , I got it connected to one of the primary injectors it wasnt easy ..
Now all thats left is the TAP .. I have a greddy elbow
now my thoughts are I bought a used model , and it has a very very little bit of thread on the injector where does that thread onto? am I uspposed to drill and tap the elbow then screw it onto that? or am I supposed to usea NUT and screw the nut onto the thread of the injector?
and if I'm supposed to drill and tap is what sized bit and tap do I use ?
