The problem is the rubber bladder. It has broken down over time. Sealing the bulkhead won't repair the problem. I tried that by sealing the bolts with Hylamar (sp). Worked as long as I didn't fill the tank above the bulkhead. Eventually, the tank began leaking out the lower left weep hole. One way to fix the leak was to replace the bladder, which is the route I took. We removed the tank and sent it to FUEL SAFE in Oregon (who made the unit) to be replaced. They will then make a new bladder for the tank install it and certify it for 5 years, then mail it back. The turnaround time is 8+ weeks. It is highly recommended that you replace all of your fuel lines and filters and flush out all of the fuel system because it has now been contaminated with the breakdown of the bladder and the foam. Plus, the fuel lines are more than likely breaking apart internally and hardening from age and the fuel contamination. How do I know all of this? I'm going through it right now. There may be less expensive ways to get around this, but I wanted to keep mine the way it came. The reason mine lasted so long (23-24 years) is because I have only used racing gasoline (112 octane) in the car. I have been told that it is better for the rubber etc. than 87 octane as well.
