Unfortunately, I can't. The trash came today.
However, mine was very yellowed - the way old plastic looks when it sits out in the sun too long - and the cracks were hairline fractures that I mistook as scratches. Closer inspection though revealed that they were indeed cracks and went all the way through the plastic on the underside of the tank. It didn't leak with fluid just sitting in it, but under pressure, it was squirting out and spraying on the belt - which in turn flung it all over the engine compartment.
So, I'm not 100% certain that my water pump needed replacing, but I'm glad I've got it done regardless.
