    i just picked up a 91 civc hatchback and when you fill the tank it leaks full from around the fuel pump area, i would like to know if its a common problem before i drop the tank. i was just going to get a new tank and pump. but before i do i thought i would ask around for an easier fix for now

    Could be a bad/broken clamp or a cracked weld/rust in the filler neck. Or a bad gasket in the neck/tank connection. Being that it only leaks when filling, that would be my guess.

    i had a leak like that on the first hatch i bought. the damn tank was rusted to hell and back. the actual seal where the two halves of the tank were welded together is where the leak came from. if i put more then 1/2 a tank in it, it would come right back out. either that or what phyregod said.

    My hatch was doing that. I replaced the tank and pump at the same time and it fixed the problem. I found a used CRX tank and pump for $100, so I got lucky...

    It's a good place to start. Clean all the surfaces and makes sure everything is good to go before you install it back on there, and you shouldn't have any more problems.

    Try to pinpoint further where the leak is coming from. I kept on having a real bad leak and I found it to be a bad fuel line. Put a new hose and clamp and still leaked. It was inside of the metal line that was rusted. Car came from ohio so had rust every where. But just take a look and make sure before you start spending money.
