I guess it's never a good sign when it drips under the car and smells like gasoline...  But in my case it's not as bad as it could have been since I can drive on LPG as well. I've driven up the gas, so that I won't risk exploding on the highway. But I wonder if there are any standard problems, like gaskets, tubes or stuff. The dripping comes from the left side (furthest from the pipe, luckily...) and it's not pouring, it's dripping, but maybe one drip every 2-3 seconds after driving. Then it stops. I have to take down the tank to know for sure, but it comes from pretty high up, I can see that it's been running down the side of the tank.
Are there any standard errors on this, so I can assume that it's a hose or a gasket, or do I need to fill it up with water and start welding?

Do you have issues with rust due to road salting/chemicals where you live? It could be the hard lines from the sending unit have rusted through.
Sometimes the O-ring under the sender hardens up and begins leaking but that's at the top of the tank and wouldn't likely keep leaking for long after movement stopped, just when sloshing around.
Could be as simple as one of the hoses just isn't properly secured to the hard lines.
Suburbans sometimes have a big metal tray (especially the 4x4's) under the tank as a protective shield so if it's leaking from that, gonna be hard to tell where it's coming from until you pull the tank down.

Yeah, there's a bit of that old salt going on here. Thanks for the tips, I thought the big metal under there was the tank itself. Maybe there has leaked out a lot into the metal tray, so I was driving a big bomb!  Anyway, I guess I'll have to take down that tank sooner or later. Thanks!

Just got done replacing my 95 Suburban Tank... Might as well figure on replacing everything..including sender, fuel pump, pickup screen, all lines that are rusted. The bad news is after all that I can't afford 42 gallons of gas to fill it up......

I'll replace/fix only what I absolutely have to do. Going to sell the thing soon anyway. I will tell the buyer that I have fixed the tank, but nothing else. I'm a cheap censored guy, but not a lier.

Starting to think that it's the line from the pump. It seems to leak even when it's almost empty (so empty I can't drive reliably on it because it looses gas in turns), so that may indicate that it's not the slushing around but the gas pump that's pushing it out. I do have an electrical pump on this car, right?

Yep, electric pump, inside the tank attached to the bottom of the sending unit.

Thought so, thanks. Unfortunately it doesn't seem to be that easy. I removed the fuel pump relay under the hood, and it drips no less for that.

Thanks, but the prices are rather different here. Around $500 is more probable.
