My 91 EGT leaks between 3/4 and full. Looks like it's coming from the top of the tank. It smells pretty bad too. :? But below 3/4 it works fine. I was going to wait until I needed to do some exhust work before I messed with it. I'm I safe to wait or should I address this soon. I rarely drive with the tank over half. I was also wondering where to get a replacement tank (just in case), looks like no one sells one for the 91-96 model years. would that tank from an LX work on this?
