Big Turbo GMC Needed A NEW Fuel System - Then kills its 4L80

I have been working on this video and the truck progress for over 2 months now. I officially started chasing fuel pressure issues back in July '25. Rule and practice number one, make sure you have good data, verified by a second source. living this rule would have saved me a bunch of headache, at what point did I fix my issues? not sure, but its fixed now. As soon as it gets fixed, trans is junk, at least I THINK. Hopefully we can get it sent off and back before the season ends.
