I am planning on finally replacing my injectors this weekend. I am reading that I need to replace the feed/return lines that supply the fuel rail, and also the o-rings that connect the 2 sides together with the fuel pressure regulator. I also plan on replacing the diaphram this weekend as well (already have), but am confused on which o-ring kit I need to complete the task.

From my reading(s), it appears that I would be best off with the "kit". I have found what appears to be the "kit" @ O'Reilley's and AutoZone, but they don't have it in stock.

BWD - Fuel Injector Seal Kit

This kit appears to be similar in appearance to the AC Delco kit,
Am I on the right path or do I need to look for something completely different?

I will try the local Chevrolet dealers to see if they may have the AC Delco kit on hand.

These are the actual sizes required if you come across a place that has Viton O rings for sale individually
