if your having issues then read through this...

if you pump it up until you feel some resistance on the pump then you know its pressurised. if it still wont feed petrol through then the genny is blocked.
if you get no petrol flow then gently open the petrol filler cap. there should be a hiss as you release the pressure. this will tell you the seal on the pump is working and the seal on the petrol tank is ok. if there is no build up of pressure, and no hiss when you open the fuel cap then the pump washer needs oiling/changing.
you can buy a new genny [about a tenner] but always best to try and clean the old one, as youve nowt to lose!

below is a more detailed breakdown of the problems, and the fixes...

if the flame is orange then its not burning "clean", which means a good balance of air and fuel. the blue flame shows its working correctly.
to get it to run clean you need to have;
clean unleaded fuel.
pressure.
working genny.


to check the fuel is clean empty the petrol into a clear plastic [wide mouthed] bottle and look at it. i always fill my stove from fuel container into plastic bottle with a filter funnel. then into the stove.
i add a small amount of redex injector cleaner [from a car shop/halfords/etc] at the recommended dosage. do not overdo it as you will gum up the stove!
[the fuel should just change colour and have just a tinge of pink to it] use 5ml to 5 litres, but no more!

to ensure you have pressure check the pump washer is not split, and smear in some light oil. check the fuel cap seal looks ok. you should feel the pressure build up and it become difficult to pump. then you know its holing pressure.

the genny is a hollow tube that allows the fuel through. as it flows along it turns to vapour due to the heat of the stove and the pressure in the fuel tank. there is a thin wire inside the genny that runs back and forward as you turn on and off. this is to try and de-coke the inside of the genny to ensure a easy flow of fuel/vapour.
it is easy to clean an old genny by carefully extracting the wire and cleaning the gunge off with the edge of a knife. be careful not to dig it in and kink the wire! put the empty genny into a small pan with some boiling water and a spot of fairy liquid. this will clean out most of the residue.
thoroughly dry and re-assemble... sorted.

I guess thatís the only place to start, I noticed itís taken a bang on the top of the generator and pushed it inwards if that makes sense as thereís a small dent in the tank just below it and it looks like petrol has leaked from there at some point.

Could be a blocked generator?
The pressure is obviously there & it seems like there's nowhere for it to go...
Try removing & cleaning the generator with the method above or a new one is £16-£20 depending on where you shop?
I've just had mine serviced at the Tacklebox Kent (another option?).

Got my Coleman feather out earlier and started to give it a pump and petrol started to spurt out of the little hole when I removed my thumb from pumping. Iím Obviously getting pressure but why is it forcing the petrol out of the pump handle. Any ideas what the issue is and how I can resolve this?

Leather washer is much better for building pressure, oil with olive oil. Buy from ebay.

If the seal washer is rubber can it be replaced with leather? Also is there a good place to order spares like this?
