So has anyone heard of anyone having a failure with a system saver installed to give any feedback on if it worked or not or how long after the injectors lasted?
My fear is that the 20 micron screen may save it but for the time it takes for the screen to get plugged off how much of that smaller material gets through to the injectors causing damage that may show up down the road?

10k Canadian is about what my gm mechanic friend told me it costs for them to do it.
This is the kit you need though if you are tuned or going to tune it

AC Delco pump kit part # 12672028 is the kit you need if you are going to keep the cp4. You can probably save yourself a bunch of money by purchasing online somewhere rather than paying dealer markup on it.

As a sidenote, I recommend anyone who has experienced this problem to report it to the NHTSA. I just reported my incident and if enough continue to do it GM should issue a safety recall. Losing all power, including power steering and brakes while at highway speeds pulling a 20k pound loaded trailer is nothing to sneeze at. Fortunately I wasn't towing my usual load that day. GM lists it as a "hard start, no start" issue which is BS. These fuel pumps don't explode when the engine isn't running.

The chance is always there, even if you have a lift pump. Some people have made it hundreds of thousands of miles where others haven't made it to 100k before it goes. A cp3 swap isn't hard, just takes some time to get at it, and it's cheaper than what is needed after the cp4 let's loose.
No lift pump yet, only a mild tune. But my DPF and cat went out at the same time only reason I deleted. Dealer wanted 5300 to replace both
