It is used to supply a consistent vacuum to the brake booster. In engines with variable valve timing there is not always a consistent vacuum pressure in the intake manifold. This could be a loss in pressure resulting in a loss of brake booster. The 3.8L engine used in 07'-11' does not have variable valve timing and so the brake booster is fed directly off of a line from the manifold, no vacuum pump needed.

You would think that the engineers have to know that people are going to modify these things and one thing at the top of the list of first parts to go is a front bumper. They had to know that this was going to get in the way....
if you do move it, i'd suggest the evo relocation kit. i moved mine under the hood trying to be cheap, but the noise it makes bugs me. so i ordered the evo kit.
As mentioned, the EVO bracket is what I would recommend but, I do know that OverlanderJK just flipped his and it seems to do the trick too.
It makes a noise? :thinking:
mine makes a buzzing sound mostly ar start up then goes away. i think when it turns on it builds pressure.:idontknow:
Have the Smittybilt XRC MOD front bumper and winch installed. Did not have to move the vacum pump.
