Question about Coleman Cable Coleman Twomantle Dual Fuel Powerhouse Lantern ()
I've dismanteled, but still the pressure remains fixed (cannot pump any more without pushback). When I have the first section in the base; and the valve is open (or without the knob installedI just pushing down on the exposed gidget) I get a very small gurgle of escaped air/fuel (I've emptied the can before starting). Behaves the same whether fully assembled, or just down to that first pipe. How do you release the pressure that's been built up? And more importantly; what could be preventing the pressure from releasing? I thought it would have released when I took the fuel cap off but that doesnt seem to be the case? Thanks!

It sounds like you are correct. While I don't know much about the new lanterns I have worked a lot on older ones. My first suggestion is the easiest. Try putting some 3 in 1 oil on it. First relieve any pressure in the tank- open the valve then slowly loosen the fill cap- watch out as it will likely spill fuel so do this outside Remove the plunger, there is a black plastic piece that holds it in it will come of either by a push and twist, or by removing a little metal bail across it. (you remove the metal bail (small wire loop) by gently pulling it outward with a small pliers.) then the plunger should come right out look into the hole and you will see a check valve at the bottom, try a bit of oil or wd40 on this, let it sit for a while, it may just be rusted open, and will take some time for the oil to work. Make sure it is working well before you light the lantern. you Do Not want this to fail when the lantern is going. Do this outside and away from any flames. Pump it up and see if it can hold pressure overnight
