Thank you all for your contributions to this question. I know about the flex line from the tank petcock to the hard line attached to the frame, but I would have thought GM engineers would have also installed one at the fuel pump.

My truck is not a numbers correct build so in addition to the flex line at the tank, I’m going to install one at the fuel pump.

Thanks everybody for your input!
