i installed the check valve in my fuel line and my son purchased a street performance 500 cfm 2 bbl carburetor for my truck and after installation the only actual adjustment i needed was to set the idle. very nice and will most definitely purchase other products in the future.

I started using Evil Energy products a little over two years ago. I have all my flex lines, catch cans, breathers, and fuel filters are all Evil Energy. When I first received their products I didn’t have any instructions and I had to learn about AN fittings from other manufacturers. Now with a couple years experience I help others learn about the product and help them to determine not only what the need but how to install and complete their projects. I was a trainer and SME in the natural gas industry and enjoy helping others. I wished Evil Energy would have a service contact number to call but I understand their reasoning. I had told them I would even help set it up here in America. They could hire regional experienced people like me and offer more help. Once you learn the system of the parts, the customers would be off and running for success. I believe it’s a lot better now with instruction coming with most kits. Very helpful for new customers who don’t have the experience. I’ll give Wvil Energy 5 stars!
