I have been told that there are 2 different tanks made by 2 different company's,ones has a painted top and the other is galvo don't know how true it is.Has anyone brought the ones selling on ebay??
I bought one of the repro XU1 tanks off of ebay & fitted it a couple of weeks ago(into a 4 door SL of all things). Seems pretty good so far.. Certainly seemed to me like a better option than stuffing around with all the old tanks I looked at that are well past their use by date and will likely give you trouble. I just didn't feel like wasting time with another leaking 2nd hand tank. Guess it depends on whether you feel like forking out the $$$ because they ain't cheap but are OK quality.
