If so, what do you think about its quality? price? Also, is anyone running their new one way valve that just gavity feeds to the oem tank which means you never have to flip a switch? How is that working for you guys? thanks

I have just the RDS 37 gallon fuel tank (no tool box) with the 6 way switching device. Quality and customer service were excellent. With all the fuel that gets returned to the tank, I was concerned about overfilling the factory tank; I liked that the fuel returns to the tank it came from with the 6 way switch. Also, if you get some water, hopefully it would stay in whatever tank it was put into and not contaminate the other. Just something to think about.
