I have a Coleman 442 but when l cover the hole on pump it seems like it's at full pressure can anyone give me any advice l am a complete novice to these so any help appreciated thanks
@Ali P have you unscrewed the pump knob about a turn or two before pumping? The shaft of the pump is hollow and rides on a spindle that seals the bottom of the pump as a safety mechanism when the pump is not in use. There is a non return mechanism but this additional arrangement is a belt and braces way of stopping petrol squirting back into the pump of the non return fails. Unscrew the pump head, pump with your thumb over the hole. tighten back up once you have sufficient pressure. Regards John
Here’s a beginner’s guide to your Coleman 442. It’s a good stove. With a little repair work it should be running reliably again. First the obvious stuff. Read and follow the startup instructions printed on your stove or from the Owners Manual (a folded paper flyer). If the instruction decals and/or the Owners Manual are missing, search this site’s stove reference gallery to download copies. Coleman also has Owners Manual downloads available from their website. If the pump is still stuck, that means the check valve (at bottom of pump barrel) is stuck. A common issue after a long storage idle. Remove the pump plunger. Spray penetrating oil into the pump barrel. Soak overnight. Reassemble and test the next day. That usually works. If pump still cannot pump air, search this site for “coleman check valve removal.” Best of luck with your new 442!
Here is a link to the owners manual; https://classiccampstoves.com/threads/coleman-442-manual.33547/ Also, your location is listed as UK. Per UK members, Coleman fuel is impossible to get there. They substitute “Aspen 4T” (not “Aspen 2”) or “panel wipe.” These are cleaner burning fuels than automobile gasoline. If you must use automobile gasoline, best practice is to empty the tank prior to storing the stove between trips. Gasoline left in the tank for a long time will gum up the pump check valve.
Thanks for your help lads pump now working but l think generator not working now as when I pump it up no fuel comes out but if l remove generator pipe and open tap fuel comes out can't get any movement on pricier wire should I be able to pull it through thanks again for your help think l was robbed buying it lol
Suggest replacing the generator. Coleman generators are designed to be wear parts, replaced when they eventually plug or are damaged. You can try cleaning your existing 442 generator. Success rate is low but worth a try. Treat the old tube similar to a gummed up carburetor part. Soak overnight in carburetor cleaner or fuel. Or put in an ultrasound cleaner if available. Then try blowing compressed air both directions. Repeat until successful or you give up. Some owners report success with heating the brass tube red hot, followed by water quench, then compressed air. Success rate is still low. The carbon deposits inside these small diameter bent tubes are very difficult to remove. The fastest and most reliable fix is to replace the generator. For future reference, the additives in today’s automobile gasoline will plug generators much faster than clean naphtha fuels. Gasoline is the cheapest fuel, but the trade-off is shorter generator life.
Will try cleaning is there any alternative copy generator after market alternatives thanks again for your help
Tony beat me to it! Old Coleman Parts > Generators > Stove Generator- 400B/440/442/508A/508B/533 - C013 Sorry, no aftermarket copies I know of. Check e-bay and similar. You never know what might pop up. Or switch to a Trangia alcohol stove & cook kit. No moving parts. No pressure tank. Very common new & used in the UK too. That’s what I use for anything short of winter camping conditions.
Thanks lads for all your help l have tracked an old stove down on ebay and assured it has an ok generator so hopefully I should be sorted but will keep looking back on you lads for any news and gossip cant understand stove being sold as unleaded fuel if its known to damage them lol thanks again Ali
