Tip: When the pump plunger is tightened too much the valve seat can be damaged, resulting in minor pressure leaks.Once you've determined what is causing the leak, repair kits are available for the cap, plunger, and valve.If the stove has been stored for a long time the cup may be too dry or damaged to rescue.When repairs are complete and you've refilled the tank and pumped up the pressure, tighten the plunger clockwise before use. Too much pressure on the valve at the end of the stem will damage it and cause it to leak pressure and fuel.It is best to fuel and pressurize the tank while it is removed from the stove.
The critical issue is for the cup to be flexible, without any perforations on the edges that could allow the pressure to bypass down the cylinder wall.
Safety Tip: Coleman fuel is very volatile and fuel leaks can lead to a fire outside of the burner, which can be very dangerous.
After any repairs, before you strike a match, make sure there are no fuel leaks.
