Yeah the pump is unopened. It is used ,but, was running fine whenever it was pulled. I had 3 C6's tore down at once and we built 2 good ones with all the parts. Then another C6 went down and we built that one as well. I have a bunch of parts laying around. I just couldnt throw them out. Somebody might need something and it would cost them a bunch of money to buy it from the parts store. Send me your zip and I will get a shipping quote for you.
