thanks Hatzie, that's exactly what I need - but am kinda hoping there's an available test part out there that does this, otherwise I'm cobbling together a homemade set of GM push-fit metal clip lines to get the job done - and the seal is critical since I'd be testing pressure bleed-off post pump power down. Haven't been able to find such an animal - and maybe incorrectly assumed it'd be available off the shelf. I'd have to assume a GM mech doesn't cobble together something whenever they are troubleshooting this at a dealership, so seems it should be out there somewhere. I may need to look a little more, might be looking in the wrong place.
