fuel tank prices are crazy

Afraid I agree with PipeDreamsMarine. I am a fabricator, and that tank will take two(2) sheets of 5052-H32 .090 aluminum at a cost around $100+. Add layout, pressbrake work, baffles and fitting, fuel fittings, sender ring, etc., add on tig welding (gases, rod), testing, insurance, and lets not forget wages, and it adds up. We don't price work by the gallon, but by the effort and cost of materials. Could build a 100 gallon tank instead of that 48 gallon one for about the same money. West Marine will quote you a custom built tank in 1-2 days if you fax them the dimensions. Have you tried this?
