Gas tank accepts a left side 3/8" National Pipe Thread petcock, and has a fuel capacity of 3.0 gallons. It features a curved underside, and dual strap mount kit with bushings. Check the tank for flaws and fit before painting. Do not grind or sand the seams or joints. Clean the inside of the tank. It is suggested to pressure test and use a tank sealer. We suggest using Kreem gas tank combo kit to clean, condition, and seal to help stop leaks and prevent corrosion. Check petcock opening, making sure the petcock can be easily installed. The petcock fitting should be masked or plugged during painting for easy installation of the petcock.
