Worked great! Review: Worth it! Buy this one - I used a little pipe dope to put the gauge in the cap, but it might not be needed. Clamps feel good quality, it fit snugly together and perfectly in my 3rd gen swap 4th gen 6.7 Cummins. This was exactly what I needed with the angled valve stem, that was a game changer as space is limited but I found several leaks and fixed my issue. Good quality for a fair price, easy to assemble with no leaks. Iā€™d definitely buy it again if I lose this one. ## Features - Your turbo engine just not pulling as hard as it used to?!
