I'm definitely going to fix the yellow line, since it's leaking on the metal side it will be a major pain though.

The red one is capped where the tank is, I just figured it would be where the hanging red hose is supposed to go.

Where the yellow hose connects to the fuel tank, I cut the rubber jacket but there is a plastic hose inside which I can't get off. I have to replace the hose because I cut the rubber part, is this hose a pre-made assembly or do I have to get a fitting and make my own?

 

Ok, it's been a few days because I've been working but I have learned a little more info.

First, the hose marked in red is part of the evaporative emissions system, that hose is supposed to run to the charcoal canister.

Also, I think my relay is sticking, so I'm going to try a new one. Now I just need to replace and repair my fuel lines and put a new in-tank pump and filter in. We'll see if that cures my issues.

 

I had the same problem on my 85 GL. It sat for 5 years in AZ with 1/2 tank of gas in it. Turned out the in tank pump had rusted so the float would not go below 1/2 tank. Ended up replacing the entire tank and pump due to rust throughout. Not cheap.

 

I finally got the pump assembly out of the tank, and I immediately had a "well there's your problem" moment.

It appears my in-tank fuel pump isn't connected to its respective output line as you can see here: http://img20.imageshack.us/img20/7757/p1030264x.jpg

Now it would appear I need a new set of rubber bindings to hold the pump (which I'm replacing for good measure) to its pipe. I also have a leaky fuel line an need a new line from output to metal and from metal to return... I'm not sure how to go about that, especially since I can't disconnect the rubber return line from the metal line (which is leaking!) no matter how hard I try... Its really stuck on there!

 

Totally called it. BUt I would replace the intank pump while you are there, that thing looks like it has seen better days. Also, usually when you buy a new intank pump it comes with all the new rubber you're gonna need.

 

The job is done, I've replaced the fuel pump and the fuel line. My car runs better now, though it still needs a tune-up. The hesitation is almost completely gone, it's just barely noticable. Thanks for the help guys, next stop is a fuel filter, plugs, cap, rotor and wire set.
