My tank has been out of the truck for sometime now. Two summers of sitting under a tarp in the heat. The other day I dropped the tank off at a shop that is going to boil out the inside of the tank, fill any holes with metal, then seal the tank. Currently been using a 15 gallon tank I bought off amazon. It does have a sensor but I don't have a gauge attached which makes checking and filling fun. Im just happy the tank wasn't as rusted out as I thought it might be. So far only the one pin hole but I guess I will see when the tank is finished.
