My stock tank is in the attic. The Safari isn't going anywhere
IMS has a couple options that are cheaper than the Safari. If I were to do it over again right now, I'd get the IMS 3.0 gallon. It uses the stock side panels and I have never had to put more than 3 gallons in mine when I fill up anyway. It's usually 2.5-2.75. It doesn't need an auxiliary vacuum fuel pump either.
