i guess I'm a little confused on this. AGK is showing an install going into the engine side cover and also the valve cover on a pred motor saying it gives off enough plus. I'm using a briggs motor but figured the same as far as going into the side cover? but if the manifold works i don't see why i can't just do that.. this is my home made one now. so would u recommend me drilling and tapping a fitting right into the bend on mine for it to work?
