I also built my own tank using parts and information supplied by Vaporworx. Did I save money yes. Does mine look as good as Ricks, NO. Don't get me wrong, ours turned out very good and is custom built for our application. However, it is a TON of work. I never expected it to be nicer than Ricks. I have built 1, they have built........well think of the McDonalds served sign. We did ours to save some money sure, but we also did it because I love to learn and I thought this was one project I needed to tackle. After having built one myself, I would not turn my nose up at the cost from Ricks. You would not be disappointed. Oh, and you are not comparing apples to apples with the other tanks mentioned. The technology in the Vaporworks system matches the needs of today's fuel injected engines and the driving style we all admire on this site. Fuel control is king and this system is the best out there. Good luck with your project!
