alright, i forgot to take ANY pics along the way. but to document it for future searches...
the rear drive shaft had to come out for fuel tank removal, and the rear tank strap was rusted so bad it came out in 3 pieces. luckily one of the local parts stores had them in stock.
As far as the flex nylon fuel lines go, they seemed very well built and were plenty long. It was a blessing to only have to work with brand new quick connect fittings and no rusty lines. The main line is 2 pieces, tank to filter, and filter to fuel rail. The return line goes from fuel rail to tank. And the vent line goes from the back side of the drivers side head, to the charcoal canister. I left the old stainless lines in the truck, to use as an anchor to zip tie the new flex lines away from things that are hot and/or spinning. Removing the front drive haft opens up a lot of room to route the new lines up the firewall. The whole job took about 10 hours total, but I'm no speed demon. just glad its fixed, runs great, and no leaks.
