I have a 93 gmc sierra k1500 with the 5.7l 350 engine in it. I recently changed the intake manifold on it and the line that runs from the brake booster to the intake doesn't fit. The new one requires a 1/4in nut to screw into the manifold, and the old one is what appears to be 7/16? I couldn't find an adaptor for it anywhere. So I am kind of stuck here. Any ideas?
