Yes built in the USA! I got prices from 399.00 to 750.00 to build this tank. That is why I almost did it myself. A sheet of 5051 .125x4'x10' Aluminum is $150.00 sending unit $40.00, Fuel Cell Cap $40.00 and 5 Aluminum an Fittings are about $30.00. So I would have had $260.00 in parts but would have had extra material for another 2 tanks. Driving to pick up material. $50.00 for fuel, so that is right at $310.00 plus my time to pick it up and build it $200.00 per hour, you get the picture. So I went with the guy that looks like he does the best work. I paid $450.00 for the tank plus shipping so a little over $500.00 total. Should be a sweet tank when its all done.
Plus so you know the pre built tanks are using .090 thick material.
