Discrepancy on location, I am convinced there are two total but location is not clear. Are they under the manifold or in bank 1 and 2 alongside motor? I have the 2011 4.8L, WT, 4x4. Any help would be greatly appreciated before I get too involved. I am hoping they are on the sides because, then I only need to remove wheel well coverings to access, if not that intake manifold does not look fun, albeit I did replace one on a Chevy Trax once successfully (Tags and kids paint keep the hoses in the right place, LOL!). Thank You, Blazin Blake
