Hi i recently bought a Coleman latern i believe to be a 335p if someone coulkd confirm thats the right model ? Latern is made in Canada, stamped 1973. Im a complete newbie this is my first latern. I have a few questions, wich i'd appreciate some light shed on Has my latern been converted from coleman fuel/petrol to kerosene? If so do you fill up the pre burner cup and the font with kerosene? I need a new mantel and im unsure what size mantel i need? From the pictures is there anything else missing from the original lantern thats essential for day to day running? Ive done a few bits to the latern like lightly cleaned, taken the pump out and oiled the leather it holds good pressure and and hisses when i open fuel cap.Bar this is this anything else i should check/clean/ replace before seeing wether it works? Thanks so much for any information on this lantern im really keen to get it working! Nathan

If it is marked 335 on the collar then it's a 335 which looks near enough the same as model 339 so may have been fitted with a model 339 kero generator and pre heater cup. Easy enough to check. The 335 generator tube is 0.25 inch Dia with gas tip marked 6 and the 339 generator is 0.31 Inch dia with gas tip marked 3. 335 is an instant lighting gasoline lantern so Coleman fuel or any equivalent naphtha in the tank and whilst it should light without pre-heating will be easier to fire up with a little meths in the cup. 339 is a kero lantern and has to be preheated but the pre heat cup requires an alcohol. Kerosene in there wouldn’t light and if it did would make a lot of black smoke. The correct mantle is a Coleman 99 but any equivalent 350 cp mantle will work fine. The lamp will run safely on gasoline or kero but before any trial run do an under water pressure test without fuel in the tank and operating all the controls. As an instant-Lite with naphtha fuel it doesn’t require pre heating. Just open the valve a quarter turn and light then when the burn settles open the valve fully. For anyone not familiar with these that can be a bit startling as there is always some flaring and spluttering and if you are a bit slow appying the match a hefty whoomph. So perhaps better to light as you would with kerosene in the tank by filling the pre-heat cup with meths and after it burns almost down open the valve. ::Neil::
Cheers for all the info im going to look up what youv'e explained like ive said this is my first lantern so im super green!
Yes an essential test before using any newly acquired pressure lamp. He talks Coleman and doesn't mention some of the other problems that can occur but finding bubbles before leaking fuel is the idea. ::Neil:: We crossed with that. So 339 is what it looked like which makes it a kerosene burner lamp. Find and fix leaks first then with around 10-20 pump strokes in the tank pre-heat with meths and open the valve. ::Neil::
Once you've done a dunk test, and assuming no leaks were found, reassemble it and add a 350cp mantle. Once it's been burned in you fan fill the pre-heater cup with meths ready to pre-heat. As it has a positive shut off valve you can add pressure before you start so when the meths is used up, open the control valve and it should start just fine. One thing about Coleman lanterns is 99 times out of 100 they 'just work'.
I always change the fuel cap seal on any Coleman that comes my way. Call it peace of mind and removing one more thing out of the "what went wrong" paradigm. I use the ones from the fettlebox. Chris
