Default lift pump fuel line

I bought this truck yesterday and it ran fine on the way home.
I went this morning to get a state inspection sticker and it dies on me about 5 miles down the road. I had it towed home (ouch, not off to a good start with this one)

1. the main tank is dripping fuel and the bottom of it is mostly wet from the middle on
back. if I siphon the fuel out of this how hard is it to drop? I see the front bolt is under the carrier bearing. what am I likely to find? are these leaks common?

2. the wiring on the passenger side between the battery and the firewall has all been spliced with a couple dozen butt connectors and wire nuts, but all the lights worked yesterday and it was starting and running fine.
battery terminal (negative) on the drivers side battery is loose enough to spin back n forth.
I need to replace cables or at least new end on the negative.

3. Disconnect the fuel line from te lift pump at the ff housing and nothing comes out when I crank it. there's a rubber cone washer there that's disintegrated..
can I just get brass fitting for the lift pump and ff houing and do away with this line?
looks like it has a heater built into it?


I'm semitired and have more time than money but not sure about parts and where to get them.


many thanks in advance.

Paul

COmmon fuel line leaks spot is right at the selector valve.

The fuel tank drops by the 2 straps holding it up and the skid plate if it has 1.

The line from the from the lift pump to the FF can be chnaged to brass fttings and rubber line.

Fix the first fuel leak by the tank and if it still doesn't pump replace the lift pump
