Follow up: I replaced the lift pump that was quite old, if not the original. The problem resurfaced so it looks like I need to clean the tank.
Questions; I had heard from a previous J30 owner that there were baffles in the tank. If so it would seem that cleaning it out would be more than just opening it up and wiping out the gunk. Has anyone come across that type of tank? Also, after the tank has been cleaned, do you need to flush the fuel lines? What do you use to reseal the inspection plate? Can the tank be cleaned in place, or does it need to be removed?
Thanks,
