Installed one of their tanks in ayliar's 70 300 TNT. He may have to Massage the seems down with a two by four and A dead blow hammer. Other than that the tank itself it's fine. Be sure to use a OEM fuel tank sending unit. There are problems with the aftermarket items in both manufacturer and accuracy oh, just an FYI for you. Was not aware of the crack vent lines but as the photos revealed it seems to be a problem. Still their reputation is quite good and I have bought many items from them with no problems.
