I'm thinking of replacing the OEM tank on my truck with a 56 gallon aftermarket tank from Transfer Flow. They will do the install as well. Will this installation be legal in California? Will the dealer mess with my warranty? Does the new tank mess with any of the computer information or overhead display information? Anybody know or have recommendations other than transfer flow? I've heard decent reviews and they're within 2 hrs so I don't have to mess with the install. Don't want a tank in the bed as I need the space. Any and all input or experiences with this setup is appreciated! Thanks!
