In the kit there are two lengthened studs for the UIM. It says use two nuts to tighten them like in the previous step. I have a torx socket so I didn't use two nuts to get the old one out. What size nut do I need to tighten them? Also can someone post a pic for step 7? It says install the coolant bypass fitting connecting the in & out coolant hose on the bottom of the elbow near the tb . I just wanna make sure its hooked up right. Thanks
