No. Most other fuel cartridges use an internal bladder system where another gas is used to pressurize the bladder to push out the fuel that injects into the tool. Unfortunately over time this bladder is compromised, so even if there is unused fuel remaining in the can, there is no pressure to push the fuel out. Our cartridge does not use a bladder system. Just a simple aluminium can with liquefied fuel inside. So as long as there is fuel inside the can, it can be used.
