I found my birthday 335 a couple of weeks ago and it's got a weird problem.  Not surprisingly, the pump leather was dry.  I left it soaking in 10/40 for a couple of days while cleaned things up and repainted the fount.  The pump leather worked well on reassembly.  About twenty-four hours later I tried lighting it again and found that the leather was just slipping up and down the pump tube.  I pulled it out.  It's nice and supple.  I folded it all the way back, then reshaped it and put it back in.  It worked fine that evening, but the next evening it had "shrunk" again.  I don't have a new leather cup, but I pulled one from a 321 that has been working consistently.  It worked that evening in the 335, but had "shrunk" the next evening.  I put the 335 leather in the 321 a week ago and it's still working as it should.  I borrowed a good leather cup from a parts stove, put it in the 335.  Again, it was good at first, but not twenty-four hours later.

It's like the pump tube is oversized or something.  If I massage the leather out it'll work for a little while, but the next day it just slips up and down the tube and won't build any pressure.  I'm thinking of seeing if I can find a washer that will fit inside the cup or cutting a custom plastic washer--something to give it a little more diameter.  Has anyone ever had this problem?

If you have room pull the clip or nut off the pump shaft at the end of the leather pump cup. Add a thin washer (brass from Ace Hardware is good) just a bit smaller than the leather inside diameter. Should retain shape just fine.

when this happens to me i just usually swap it for a different used one , sometimes a new one , thicker or stiffer . i did add a cup spreader to a euro style once . i really doubt its the tube diameter .

It's weird.  The leather works just fine in anything else and leather cups that work fine others don't work in this.  I keep coming back to something being screwy with this specific lantern's pump tube.

Like Steve says, it likely ain't the pump tube. Near impossible.

Hey folks first time poster and a reacent aquirer of my first to lanterns nos supposing I've remembered it wight I have a 228A built in 91 i recieved for free and and a 335 built it 73 or 76 I bought in non working condition for 18 bucks on kijiji... yes I'm from Canada. 

To my point the 335 seems to not be building any pressure at all no matter how much I pymp it even after trying to soften up the leather so I ordered a new pump from coleman but while thinking about it was curious if you experienced people had any other suggestions to offer 

If this isn't the spot for this im new to the forum life so please redirect me and ill happily move the conversation elsewhere thanks so much for any help you can offer

I've had these similar problems on leather cups and pump tubes as well. 
The leather would somehow shrink up a little a short while despite adequate oiling.
Maybe its really the pump tube having a marginally bigger bore. I ain't sure.
What I did to improve the workings might seem a little over the edge. Well, I applied heavy SAE 140 gear oil instead and it worked for me.

Yup, whatever gets the job done.

I've used silicone grease on the neoprene pump cups and Vaseline on the leather when needed.

Yeah. On the pump of a highly corroded and unevenly worn milspec, I found that some thick, high temperature-rated grease or equivalent instead of just oil, would be the only stuff that could get the leather cup to seal.

I would love to lol but I suspect there's a gestation period before I have the ability to create a topic being a new member to the forum but ill tinker with it for the time being and replace the pump then possibly the filler cap gasket and go from there
