Great repair.
I had to do this repair recently. I had cracks in exactly the same spot as the ones shown in couch tour's examples. I had to do it because I could not pass smog. I don't know if this is new, but your gas tank has to hold pressure in order to pass smog. Something to do with capturing the raw gas fumes and burning them in the engine, so they don't escape to the atmosphere.
I have some points to add.
When removing the L-shaped valves, (the feed and return valves), from the fuel pump, be VERY careful. They are a bit fragile after being exposed to gas fumes for over 15 years, and they will break. I advise spraying some WD-40 in and rotating them a bit before lifting them straight up. Do not hold them by the horizontal part, only the vertical part. I broke the black one. If you do break one, save as much of the hose as you can. You will have to cut it to get the old valve out.
The dealer wanted $90 to replace the black one, as they only sold it with the fuel line attached. Eeuroparts has it, but the picture is of a white valve and confused me. Fortunately, my mechanic had a black valve laying around and gave it to me.
Putting the valve in is also difficult, as the polyethylene hose is very stiff. On the advice of my mechanic, I slathered the valve tip with lithium grease and used a flaring tool to hold the hose while I pressed it in with my 200 plus pounds of weight. It went in, but it was not a simple task.
To complicate the tank repair, I had to go over a ridge in the gas tank. In order to get a tight fit, I took a nail and a heat gun and pre-shaped the polyethylene sheet to closely fit the ridge and a bit of the tank past the ridge, before priming and gluing it.
I had my doubts, but I just passed smog. And every time I open my gas tank, there is the hiss of escaping air, so I guess it is holding pressure pretty well.
