Possibly. I would need the internal diameter of the pump tube & diameter of mounting hole required in MM.
You could use the MSR pump tube as the outside form. A plug of your own making as the inside form. Then punch a hole.
Thank you everyone for you responses. I have measured my examples as carefully as I can. Here are the dimensions: The hole diameter: 6mm on all cups, including the msr rubber example from spares. Bore of pump tube: Standard duraseal 16mm Arctic 15 mm-The bore is a little smaller from side to side comparison with a standard duraseal pump. The pump rods appear identical, as are the pump bodies. Limitations are that my calipers do not reach far into the tube. Height leather cup 8 to 8.7 mm range. Rubber cup 6-7 mm Confirmation from others is most welcome. I ain't a machinist....
Today I received 2 leather pump cups from the Fettlebox. Spiritburner generously sent them free,to test. They are 16 mm diameter, for Tilley pumps, and USmilspec, listed on the Fettlebox website. They are excellent quality, and easy to fit. I will give them a neatsfoot oil treatment, then put them to use this season.

I seem to recall reading somewhere on this forum that MSR found the leather cup could get stuck in very cold weather since the pump shaft is slightly smaller at the bottom than at the top, which is why they went to the rubber pump cup with the Duraseal pump (@Doc Mark if I recall correctly?). This is at odds with the artic pump having the leather pump cup. Is it confirmed that the artic pump has a leather cup?
Thanks Chumango. The Arctic pump definitely has a leather cup. I don’t have calliper to reach the bottom of the pump shaft to measure it, but it makes sense it would be a tapered shape. I noticed the leather cup measured smaller than the upper shaft diameter. A leather cup in a tapered shaft, stored with the cup at the small end, would explain this. I have never had any problem with a leather cup getting stuck, and would trust leather more than rubber under any conditions. Since I switched all of my pumps to leather they have been trouble free. Just keep them well oiled.
As far as I know the pump bodies of the standard and arctic are identical only the seals and cup are different. Tapered shaft sounds like marketing dept BS to push their rubber cups Leather cups and Neatsfoot Oil (not silicone or petroleum) have always been recommended by Coleman for arctic conditions (at one time they hade a Arctic kit that came with leather cup washer & oil) I used to buy them all the time I probably have 8 unopened tube of oil. I've had rubber cups on Coleman stoves fail due to extreme cold while on Winter Warfare Exercises xgk its the benefit of living in Canada we understand the cold and what it takes my winer clothing is layered, my mitts & boots are issue arctic (good to -65 ask how I know) & my stoves have leather cups.
Always use neatsfoot on leather as leather does not react well to silicon or petroleum based lubes (the issued silicone water proofing used to destroy our leather combat boots in 12 to 18 months) as an alternative you can use dubbin or mink oil from the shoe store
I knew I had seen it. It's in the first post when discussing the pump. MSR Whisperlite Universal. I have some leather pump cups salvaged from old pumps, and another from a maintenance kit I got long ago before the switch to rubber pump cups. I'm going to contact MSR and ask if leather pump cups can be purchased. The cups in the expedition service kits are rubber.
I have never seen that Coleman lubricant. The instructions for all of my Coleman lanterns and stoves (1980-1988) simply say to lubricate the pump cup. They do not specify what type of oil. Of course mine are all from south of the border and maybe that makes a difference. The MSR lube is mineral oil, and instructions say to use it or mineral-based oil (or saliva).
I read a bunch of discouraging comments about prolonged use of neatsfoot oil and leather, and I stick to mineral oil.

I have a 49 year old pair of Sorel Snowpak boots that I use neatsfoot oil on the leather uppers (I still use them every year)
Thanks, @Cal I'll check those out. They match the measurements of the leather cups I have that were from MSR. A point of clarification - mineral oil is from petroleum. There are many types of mineral oil, it not being a specific definition, but they come from petroleum distillation.
