Question about fuel line/leak

[TroubleBound]

Okay i never thought the day would come when i would own a coupe, or a pignose, but some old man hit my chuki hatch shes now in the garage awaiting her sr. In the meantime i needed a ride to work, and an 89 coupe dropped into my life. (for $1100)

So after i drove it home i noticed that it smelled of gasoline when i got out of the car. Like toucan sam, i followed my nose around the car to where it smelled strongest. Jumped underneath the rear passenger tire/gas tank area to find those rubber fuel lines running underneath my car are old/worn/cracking to the point of fuel seeping through the whole line. I can clearly see that to remove the one side i just take the hose clamp off (after relieving fuel pressure), but the other side runs up above the gas tank, and i need to replace the whole line not just the part i can see. I was wondering where i can find the other end? Is it attached to one of the outlets on the fuel pump? Im thinking it probably is, but if so, then how do i get that end of the hose off. Im sure its just another hose clamp but how will i feed the old hose out and new hose in? Is there a hole on the side of the gas tank somewhere this hose goes through? PLEASE tell me i dont have to remove the gas tank. Heres some pics so you guys know which lines i mean.

I took this one from far away, just to give reference of where these lines where, thats my exhaust and gas tank and wheel there, i took the picture from underneath rear passenger tire.

And this is a little close...hard to fit a camera under there.I was gunna squeeze it to pic the cracks but i squeezed and gas started soaking through

Edit: 1989 Nissan 240sx coupe, base model, located in Richmond VA, but grew up (until 2 years ago) in Texas. <--According to the guy who sold it to me, ive had the car for 2 days now.

It goes up to the top of the tank, into the trunk, under the carpet. There is a metal square, bolted down. Take out the 4- 10mm bolts, and you will see the lines attached to the pump with a clamp.

If you want a tip for running a new line, after you un-hook the old one, clean off the end, but it up against the new line and e-tape the hell out of it. With some gentle tugging, you should be able to snake the new line in place.
