Well, the check valve got here alright, but it proved impossible to take out the old one, so I'm pretty much stuck with a brick. I tried car mechanics and metal shops around the village we're at now, none of them could extract what seems like a totally stuck valve.

Field serviceability... not impressed.

Thanks for the note.

I contacted Coleman UK and a quite helpful chap had the following to say:

[...]your problem is the check valve ( one way valve ) which is in the bottom of the pump cylinder these do normally perish over time ( i.e. years ) these cost £9.99 & can be replaced by using a 3/4 " metal file & a pair of molgrips simply unscrew & replace

I ordered the part (which btw appears to cost 25% of that in the US...) and will let you know how it goes when I receive it.

Cheers

Hi all

I´ve cooked at least 100 meals on my Sportster 533 (which I´ve had for 3 years now). Yesterday I went to bed with a cold sandwich.

Symptom: It´s impossible to do the first step (pump 30 times to build pressure before lighting the stove), as the pump will not even accept being pumped ONCE with my finger on the hole...

With the hole uncovered the pump appears to move in and out as normal.

I have drained the fuel, left the fuel cap open while pumping, no difference. It´s still impossible to pump even once.

I took the pump out to have a look and this is what it looks like: Photo of pump

As I am "in the field" (cyclo-touring in Chile) I don´t have proper oil, but I sprayed WD-40 all over the pump parts and reassembled to no avail.

1. Is this seal broken? The center part looks quite regularly shaped and thus normal to me.
2. What else could be going on here?
3. If worse comes to worst and I have to get spare parts where do I order them from? Coleman USA even though the stove was purchased in the UK?

Cheers

Alex
