A bit of modding needed
It works as intended the only issue is the tube inside doesn’t fit tight enough on the nipple inside the cap so I had to find another hose to replace it and it works perfect now 👌

Get one that has a better connection n not a cheap connection
I liked that the product worked I disliked how the product leaked even after tighting to stop it from leaking .....worked on a 2012 Chevy impala ltz n the hook up is in the back n thus thing was just leaking away in the back where it connects picture of what leaks n fails
