Hey all, i'm just wandering how the back seat comes out on a 91 civic hatch? I've tried pulling on it but the front clamps don't seem to want to let go. Is there and easy way to remove it without destroying it in the process. The reason why i'm asking is because i think the vent tube from the fuel tank is blocked and i was told its one of the copper tubes under the back seat coming from the fuel pump and i'm getting a really bad gas smell. Theres no leaks anywhere and the tank is solid and when i take of the fuel cap after its been running for a while, theres a huge WHOOOOSH of trapped vapours that comes out and that tells me the tank isn't venting properly. Thanks in advance Vic.
