There is a o ring in there that will need replacing m8 it is 5.28mm inside diameter and 1.78 mm thick according to what I've found out today as I've got the same problem
I just need to find some now as they need to be fuel resistant ones called flouro silicone so I have been told

If you try to build up pressure but you take your thumb off the timer knob and the air hisses out then you may need to service your check valve....
I'd never heard f it, but Karl Starnes shared this video with me as he was having the same issues.

How did you get on with this?

I recently had the fuel leaking out of the on/off lever and found mine had two o rings. After a bit of research the general consensus was the size you need is BS009, tried those and they wouldn't fit, so tried BS008 and on my particular stove anyway (533) those are the ones. Hope that may help someone, much cheaper than replacing the whole valve. Got mine from Seals R Us on eBay.

Carb cleaner is great for breaking down that sort of crud.

I was gifted a coleman 533 stove for my birthday. Not yet used.
Ive used gas stoves for decades and never petrol.
I saw a leon Bartrup youtube vid on the same stove and he said to use “superior” unleaded not standard unleaded petrol as the latter clogs up the generator.
Then i watched another review video of the stove and the guy was saying dont use the superior unleaded as they have to many additives in and can clog u the system!!

Help form users please as to what they use as fuel. Thanks

Copy/Paste from AI:

To minimize clogging in your Coleman stove when using unleaded petrol, here's the best approach:

✅ Recommended Type of Unleaded Petrol

• Use the lowest octane unleaded petrol available—typically 87 octane (regular unleaded) in most regions A B.• Lower octane fuel contains fewer additives, which are the main culprits behind carbon buildup and clogging in the generator and fuel lines.
• Avoid premium or high-octane fuels, as they often include detergents and other additives that don't burn cleanly in Coleman stoves.

⚠️ What to Avoid

• E10 petrol (contains 10% ethanol): While it can be used occasionally, it's not ideal for regular use. Ethanol can:• Accelerate corrosion in older stoves
• Deteriorate rubber seals and gaskets
• Leave more residue, increasing maintenance needs A
• High-octane or performance fuels: These are designed for modern engines and contain complex additives that Coleman stoves can't fully combust.

🔧 Maintenance Tips

• If you do use unleaded petrol regularly:• Clean the generator and fuel line more frequently to prevent buildup.
• Consider mixing a small amount of Coleman fuel (white gas) with unleaded petrol to improve combustion and reduce residue A.

If you're using a dual-fuel model like the Coleman 533 or 285, it's built to handle unleaded petrol—but even then, white gas remains the cleaner-burning option for long-term use

Probably jinxed it now but my current stove is a good few year old, never had anything but Aspen 4 used as fuel and regular application of oil, and it still works like a dream.

Hi all , just managed to bag a cheap exponent (442) listed as having a fuel leak from the on off valve , after a bit of reading I've seen a few mention graphite rope as the cure , but no actual details on what exactly I need or what to do with it !
Any input from those in the know would be greatly appreciated
