If the tank has a hose, it has a female plug. The compressor probably does too You will need a double male plug to connect them unless you have a female fitting on your Great White.Some people get the Great White that way.So, get the compressor hooked up and running.Close the de-pressure valve on the tank and compressor.Open the valve on your tank and watch the gauges.When you reach 4500psi, close the valve on the tank. De-pressurize the system and shut the compressor down.
