Good to know! Thanks!
Do you think that some of the less successful/shorter lasting treatments had anything to do with the fuel qulaity some of those boys were gettin? Or just flat out, they're runnin wore out tired injectors...

I would chalk it up to poor fuel, non-quality reman injectors to start with (ie non bosch injectors), or as you said they were just to far gone already.
The results I posted earlier with the bg stuff was on my injectors that I am trying to keep alive, they are stock bosch remans directly from chevy. I have about 50K on them now and I run the BG stuff every 66-12 months and it seems to keep them in check-ish. I run a full 31.x pulse tune 99% of the time... so I'm sure that doesn't help :roflmao:. next time I'm going to do 30 overs just to not beat them so bad.

Any way to do this procedure if you have an aftermarket lift pump and ditched the stock fuel filter head?
That won't matter, the cleaner/fuel combo is going straight into the cp3/motor it doesn't go through the tank, liftpump, or filter head. The lines you use are on the driver side by the gpcm.
I disconnect the fuel lines that come into the engine bay before the stock filter. the lines on the driver side near the firewall over the driver side valve cover. the lines I use are the 1/2" feed in and the 3/8" return line with the quick disconnects. (need the special fuel line tools to disconnect them)
In your case you can still do this procedure, the fuel just wont be filtered. I bypassed by filter because of having a lift pump also, but left it on just for this purpose and/or the lift pump failed I could still swap some lines around and still be covered.
I think what he is saying is how do you get the fuel to pump in to the motor once you disconnect it all, I had the same problem on my old truck, I had to pressurize the tank I had the cleaner in by using my air compressor and a towel with good pressure on the hole. it was just enough to bleed it through the relief valve next to the alternator. then it started up. But before I did that I couldn't get it to fire.
Use the liftpump to feed the motor once you are done... There is a bleeder on the motor on the pass side.
I think what I am going to do is hook the filter head back up and just set it up on top of the motor. Prime it w/the Fass, then disconnect the power to the pump. I just don't like the idea of running unfiltered fuel into the engine.
Doing the Gm injector cleaner as soon as it arrives, I will post before and after pics of my injectors balance rates with the same exact start up and idle time.
Plan is as follow.
Saturday Morning Start truck, drive to a destination then return. let idle for 1.5 hours, Check balance rates after one drive around the block.
Sunday morning Start Truck, Repeat, but instead of idling with regular fuel it will idle with the injector cleaner mix. Drive around the block exactly like I did the first time then check rates.
Should be a pretty controlled test to give accurate results.
My #5 injector is hurtin, so I hope this helps
