Hi all, thanks to everybody who took the time to post some help.
I know it's been a while since I've updated the thread, just haven't had much time to work on the truck. I did get some time this weekend and here's where we are at.
I replaced the two fuel lines from the pump to the tank, and also replaced the rubber line that connects the tank hard line to the frame hard line. I also replaced the fuel pump with a NOS AC pump that I had.
Fuel flow to the filter bowl increased and the old stovebolt seems a little happier. Crossing my fingers it last for a while.
Just another short video of that fuel bowl level change.
