A few years back I ran across some documentation on a Primus / Century
Tool adapter that looks very similar to your Paulin. When I contacted
Century Tool, it seems they no longer make the "unregulated" version.
I did purchase one of the regulated ones, but it really is more suited
to the 2 burner stoves - not nearly enough output with the 3 burner.
Then, as fate would have it, I found a NEW Old Stock Century Tool
UNREGULTED adapter at a swap meet (still in the package!)
I purchased it, and it workes excellently!
I don't think anyone is making the unregulated adapters any more. If
you find a source for them, then please let me know! I would love to
have some as back-up (just in case).

As a SPAM prevention measure, you will have to e-mail the webmaster
for a userid and password, but there is NO charge for this. The group
is very supportive. This is Frank Bebb's site, and he sells lots of
parts. Someone there may be able to help you out.
Feel free to e-mail me. I have a LOT of experience with Coleman
Stoves.
My good fellow, I am a card carrying member of the ICCC. I am very
familiar with the 426B and how to run it. In fact I have 4 of them.
While they all have their moments, the one stove in particular that
was giving me problems I am sure was made on either a Monday morning,
or a Friday afternoon. :)))
Be that as it may, The Propane adapter makes short work of any
problems.
But as a follow-up, in June 2008 while I was at the ICCC Annual
Convention, I purchased a spanking new - and tested - fuel tank
assembly for the 426B! So I will be getting around to further testing.
You never know, perhaps there is a problem with the U-tube in the
stove.
If any of you ever has a problem with a Coleman lantern or stove, drop
me a line. ;)
