Does anyone have a part number for fuel injector cleaning system that will hook up to the fuel rail? Also where was it purchased and what brand is it. I have tried to search the forums but no part numbers or brands and I don't want to use a pour in the tank cleaner. FYI this is a tpi 5.7 . Thanks

 

If you think your injectors at that bad, I would take them to www.rceng.com and have them clean the units and flow test them for the pattern.

 

EBay is the best place to get them. Some are complete kits with all adapters for all cars, others are just the GM connection. Here's a sample. It's not my link, only the first one I found when I searched.
