I've done an overhaul on my omnilite stove and omnifuel pump. Here is the complete list of replacement o-rings that I used, and a few pictures. The stock primus ones are slightly different, for example cross-section of 1.6mm instead of 1.5mm. However, all seem to be working fine. I used all FKM o-rings from "Ningbo Ouling Seal Co" on aliexpress. Hopefully they hold up, I didn't find a reasonable priced domestic option. All dimensions are [outer diameter] x [cross section] * omnifuel pump - [X] 33x3.5 pump top to bottle - [X] 13.5x1.5 pump tube bottom to red nrv housing. Use screw driver to twist the red plastic part while pulling off. - [X] 5x1.5 on brass NRV - [X] 16x1 metal pump shaft to black plastic pump head body. see Primus Ergo Pump Leak Fix Info - [X] 8.5x1.5 black knurled knob that threads stove into pump head, this one https://classiccampstoves.com/attac...tion_valve_for_73223031_primus_22-jpg.259978/ * stove - [X] 11x2.5 hose t-connection to pump body connector - [X] 6x1.5 spindle valve, fuel line end, and t-connector knob tip - [X] 8x2 fuel line stopper o-ring (prevents fuel line from pulling out connector), see Primus Omnifuel - Lightning does strike twice Hope it can help someone, cheers.
Nice but o ring diameter would be more helpfull if they measured inner and cross section not outer. Most supplies list as inner measurements.
i came back here a few times - I do a lot of bikepacking and was thinking to sell kits as Primus does not - any other stoves for this?
