I bought JBG's "new" 23 gallon tank about five months ago and it was a nightmare for me. I just checked their site and could not find the tank on the site any longer, so hopefully they have realized that the tank was a complete piece of crap and stopped selling it. Bottom line avoid that tank at all costs. The old one seems to fit fine for other people so it may be an option. The tank has the sending unit and vent on the top and is a obvious lack of quality control. Also JBG lost a lot of points in how they dealt with my problems which was to not deal with them at all. No return calls or solutions or concern, only "it should fit". A 23 gallon tank in general is great to have, especially if you have any body lift to get it even further away from the ground. Good luck
