Hello Tom. I can't really answer your question but, I pulled out tank 2 wks ago and was going to buy a new one. What I found and read was a problem with the tanks spilling some and not being exact. The 69fb tank has a vent tube on the spout with a hose /tube that goes up through the truck. I decided to clean it up and paint it to keep it correct
Good luck. Bill v
