These pics aren't the greatest, but this is a tank from a 59 to 61 Cadillac Seville. I don't remember the exact dimensions but it fits between the frame rails and it has a rear fill so you have to cut a hole in the bumper. I actually had to put some angle iron in between the frame rails to space it down a few inches so the filler neck would hit the bumper in the right spot. I used a fill neck out of a 73 or so Chevy truck and mounted it in the bumper. Then ran about 6 inches of hose between the neck and the fill on the tank. You have to get a sender for a newer Cadillac tank to get the proper ohms for our gauges. I think the sender is for a 65 Seville. I would have to find the receipt to make sure. The sender also has a a pick up and vent tube. The tank also has another built in vent tube that I blocked off. I actually blocked off the tubes on the sender as well because I cut a hole in the tank and installed a in tank pump set-up to run my LS1. But that's another story. This tank is only 6 inches deep and doesn't hang as low as my bumper. Yet it holds 20 gallons of fuel.
