Maintain Your Propane Fuel Tanks

CleanTech Connection Tank Sept 2018The fuel tank is at the heart of our propane autogas fuel system. Like any other part, you need to consider preventative maintenance.

The propane fuel tank should be inspected during each regular preventative maintenance interval or, at a minimum, annually. Look for signs of corrosion, peeling paint or rock chips.

With time, you may see this normal wear and tear.

Rust or corrosion on the propane tank does not necessarily mean there’s an issue. Propane autogas fuel tanks are designed with strict guidelines to meet or exceed the corrosion and structure requirements for vehicles. But just like with frame rails, axles and suspension components, the tanks will develop rust or corrosion over time.

If operating the vehicle in higher corrosion areas or severe climates, it’s recommended by tank manufactures to routinely clean and repaint the fuel tank with a rust preventative system. If the rust or corrosion seems excessive or concerning, then it’s recommended that the fuel tank be inspected by an ASME-certified repair facility to ensure the tank can stay in service.

Keep in mind that the fuel tanks we use are built to ASME standards and are rated for the usable life of the vehicle when properly maintained. Most propulsion propane tanks are built to stricter ASME standards. This is different than DOT tanks that have a more limited service life. A propane fuel tank should never need to be removed and replaced at any point during the vehicle’s life cycle.
