Review on ACDelco 215 704 Equipment Secondary Injection by Chucky Hepler

Let's get started, for some reason there weren't many tutorials on how to remove it (almost complete) nor a manual that would give the location. I spent 2 hours searching the engine bay for this pump. After 2 hours I came up with a random manual for another GM machine with a similar pump. I have found that the system uses 1-3 pumps depending on the system: GMC, Chevy, Saturn, Poniac and if it is v4, v6, v8. I noticed that there were two overhead air pumps above the exhaust manifold. So that brought me to the bottom of the engine where "this" part should be (I found it). Well, after a long search, this part went very easily and without any complications. (Note: I changed this to 20 degree weather and used WD-40 and a small flat head to (easily) pry off the stiff hose connections, just in case). It would have been 5 stars but the packaging was 5/10, there was a small chip at the top of the hose connector (no cracks), there were holes throughout the box as the item came loose during shipping. Bottom line: it was worth it and I found that the original pump held about half a liter of water so replacing it was the only option.
