The car is a 2007 CLK 350. One of the plastic parts in the front of the manifold is falling apart, so I'll be removing the manifold and replacing it with a rebuilt one. There are some good youtube videos on the procedure, but I was hoping some of you guys might have some helpful tips.

Most of my experience is with diesel engines and I'm not sure if there is a method for priming a gas injection system after you've installed the injectors, or if you just let the pump push all of the gas and air through the system. Thanks
