My air pump is about to go out yet again, this will be the second time since I've owned my car, a '92 400E. It seems that the lifespan of this part is about 100k miles, a lifespan that is way to short, especially for the cost of the unit. I've been searching the forums and haven't found anything about replacing it with an idler pulley, which I would think someone has done.

Does anyone know if there is a bracket available, or is this has been done?
