GM original OUTLET Side Tank with the seal for 86-89 Corvette.

Figure/factor into the purchase of this part the ability of the core to withstand new pressure.. too many times we find people replacing a side tank only to have the alloy Core blow days or weeks later.. or the other side tank first.. even worse.. and the core is not worth the total sum of doing it 2 or three times over and the cost of any further damage/towing/repairs.. Just consider it.
