Retrieve o-ring in pump tube

I have an Optimus 55/155 marine stove. The o-ring is at the bottom of the pump tube--it slipped off the pump. I can see it down at the bottom of the tube.

Any suggestions on tricks or retrieve it?

I am a little afraid of unscrewing the tube. I cannot get a good grip on it and it appears to be thin metal. I don't want to break o crush the pump tube.

Thanks for your help.

A long screwdriver or similar with some heavy grease on it - to “glue” the O-ring to the screwdriver?

 

something like this?

 

Thanks! That helps!

 

Available on the bay of evil. Look for
alligator forceps.

 

Make a hook on the end of a stiff wire.

 

I've always kept a few old broken bicycle spokes that come in handy for homemade tools for jobs like this.

 

I have 2 of those. 6 1/2" and 12".

 

I got the o-ring. Thanks! I used a coat hanger w/a slightly bent end.

I wish I had known to grease the o-ring (Ahh...the fun of fettling). I think a lack of grease is what started all the trouble. I have been using my stove for six years w/out knowing to add any silicone grease to the o-ring.

 

We have a winner!!!

 

a golden O-Ring for the winner;-)

 

....or a coathanger.

Result.

 

I tried a coat hanger once- it kept getting hung up.......sorry

 

Ivan that one took me a bit. Well played, sir.
