So i turn on my car today and it sounds like it was running on 3 cylinders; its was def misfiring, so i pull the spark plugs and the one form cylinder #1 looked darker so i figured the injectors bad (the injector in #1 is missing the little plastic cap on the end) As i push my car into the garage i smell straight up gas and see theres a puddle of gas under my car...leaking form the gas tank. I havent driven my car in a month! And it wasnt leaking when it was sitting...its leaking from the passenger side of the tank and its already spilled out most of the gas...i cant see where its coming from and there's no cracks or anything....what could it be?! Is there a hose or something up there that i cant see form under the car? any help is appreciated i really need to get my car running!
 
the same thing happend to me bro it sucks. i was doing my motor swap and when i finished i started it up and it leaked all over the floor. mine had a hairline crack on the passenger side front of the tank as well. i tried to jb weld it and it lasted for like 2 weeks. i ended up switching tanks goodluck!

omg..thats my worst fear having to replace the tank! i heard its a mission and a half...do they randomly just crack? Mines spilling alot of gas...like i see it streaming down the passenger side and it made a huge puddle in a minute...it has to be all the way up there cuz i cant see where its coming when im under the car. It wasnt leaking yesterday either when i drove the car for the first time in 3 weeks!

yup and it normally has to do with tank presure hot day with it sealed it will break keep cap a little loose or open the vent
 
yea its a random s14 thing.

fuuuuuu, i actually found the crack too...well the car has been sitting outside for a awhile and i always close my cap all the way (threw a code on my integra if i didnt) so yeah i guess im not as suprised anymore lol

Anyone know someone or someplace that can replace it for a good price?
 
yea your vent line is not venting obviously. I replaced 3 in one week lol until i figured it out, change the tank and you will see the ventline on top, either find out where the clog is it or leave it straight vented.
 
Did u read what the kid posted already. Jb weld worked for a week or 2 that's it. But....

What I did was I got online for $20 was a plastic welding kit(mini iron and sticks of plastic) and I melted the hole shut. Never leaked since. But becarefull u can make it worse or even start a fire.

Yeah true but i also read other threads where some ppl used jb weld and it lasted at least a couple months so its worth a shot, only 5 bucks anyway lol

The welding kit sounds good but i dont think theres a enough room to get to the crack to weld it, but ill try it too. Do you remember where and which kit you got? i found two thru google but they didnt seem right...didnt come with the sticks of plastic either.
