Fuel leak
I have a fuel leak top side of the tank. Before I drop the tank to pinpoint the problem does anyone have a suggestion of what to look at, there are some fuel lines that run through there and I here a faint high pitch whine that I assume is the fuel pump.

Re: Fuel leak
Most likely a rusted line. If it is, I'd replace both of them all the way to the front of the car. Replace the filter too.

Re: Fuel leak
The lines are rusted. I was going to replace the filter and noticed some one had tried before and kinked the line a little bit but it doesn't seem to be leaking there, I'll replace it all any ways but I had to pull it out of the garage to day because the fumes where getting bad, backed it out into the drive where it is at an incline and it started dripping pretty good looks like the tank is busted what do you think.

Re: Fuel leak
It's hard to tell, usually if the tank leaks it will be along the seams. If I were you, I'd poke the rusty spots pretty hard with a screwdriver once you get the tank out. If it's solid, just leave it, I've seen lots of tanks that look worse than that that didn't leak.

Re: Fuel leak
Sounds like a plan. If need be Auto Zone has tanks for $108 and a lock ring for another $16, figure while I'm at it I'll take care of the rusty line's to. Thanks for the replies I'll give an update when I can.

Re: Fuel leak
One last question is there anything unexpected to look out for when I go to drop the tank.
