Recently my 93LS400 developed a fuel leak in the gas tank. First thing I did was to replace the gas cap,because it seamed like thier was to much presure coming from the tank when I took off the cap. Then I pulled the carpet back in the trunk because of the concentrated smelland found a small leak. I patched it with a fuel tank repair kit. Thought it was fixed. It's not leaking but the smell is bask. Anyone have any ideas? Thank you Larry
