8 Steps to Installing a Forklift Liquid Propane Tank

Propane is the preferred fuel for half of the world’s forklifts, offering a powerful and cost-effective solution for heavy lifting since its introduction in the 1950s. But installing a liquid propane tank isn’t as simple as changing out a few batteries. This guide will walk you through the eight steps required to install a forklift liquid propane tank safely and efficiently.


  1. Safety first: Before swapping tanks, gear up with proper personal protective equipment (PPE). This includes safety goggles that fully wrap around your eyes and heavy-duty rubber gloves. Ideally, perform the tank swap in an outdoor or well-ventilated area, and steer clear of any ignition sources, such as lit cigarettes or matches.
  2. Check for residual fuel: Never assume the tank is completely empty just because the forklift has stopped running. Make sure there’s no residual fuel in the line or fitting before proceeding. Otherwise, propane could spray your face or hands, hence the protective goggles and gloves.
  3. Disconnect the old tank: Turn off the service valve and disconnect the gas line. Always be aware of any escaping gas. Once disconnected, store the empty tank following your company’s safety protocols.
  4. Inspect for leaks: Don’t rush this step. Thoroughly inspect the new propane tank for any signs of damage, such as rust, dents, or frost accumulation. Also, check the hose and fitting on the LP gas forklift for any visible irregularities.
  5. Position the new tank: Place the new tank onto the forklift’s locating pin. This pin ensures the tank aligns correctly for the hose and fitting connection, allows the fuel gauge to read accurately, and prevents the pressure relief valve from spraying liquid propane.
  6. Double-check the valve and O-ring: Make sure the valve on the new tank is off. Confirm that the O-ring from the old tank did not get stuck or damaged during the removal process, which could compromise the new tank’s safety.
  7. Secure the connections: Attach the forklift connection securely and hand-tighten it on the tank fitting. Be careful not to over-tighten so you can remove the tank quickly in an emergency. Then, slowly turn the tank valve to the ON position.
  8. Look, listen, and smell: Once you’ve installed the new propane tank, check for leaks one final time. Look for visible frost, listen for hissing sounds, and smell for any odd odors. You can also apply a soapy water solution to check for growing bubbles, indicating a leak. If you find one, take immediate action to secure the area.
