welcome Blantka, I am sorry. My finding this thread was unrelated to your question (yours remains an open question). ---------------------- An otherwise OLD THREAD, bump In OP Pinky (unavailable) focused on pumps, his pumps i'll refer to **pump 1-5. In 2019 he closed with it is "reference"... , i add that his is the best i've seen on topic (and pinky is missed here). Some models below were available at same time. In that light I will attempt to contribute to his list with adding model #s (cross reference tags), adding year ranges may be helpful, hint hint. Adding to Pinky list, "Primus Himalaya family of expedition stoves" Primus Varifuel 3278 pump1 Primus Multifuel 3288 pump2 1st version(s) w/loop gen (multifuel 3288 avail ie April 98) sample , 1999 sample thanks Yun! and sample in box [w/(ergo debut) pump4] Primus Omnifuel 3289 pump2 sample (Omnifuel "new" in '02) Primus Multifuel 3288 pump3 gen?, (referenced above) Primus Varifuel 3278 (ergo debut) pump4 (referenced above) Primus Multifuel 3288 (ergo debut) pump4, straight inlet/gen sample, Primus Multifuel EX 3288 (ergo) pump5 red end, straight inlet/gen sample in box, Primus Multifuel EX 3288 (ergo) pump5 red end, inlet at right angle sample in box Primus Omnifuel 3289 (ergo) pump5 red end Primus Omnilite Ti 3219 (ergo) pump5 [btw also mentioned Optimus Nova pump 3 ] ---------------- ** pump 1: early verifuel only, alum. body, inlet threads into pump, valve on pump pump 2: alum. body, valve on inlet tube/hose (not on pump) pump 3: alum. body, valve on inlet, rare (short use), black valve on inlet (ergo) pump 4: plastic body, black end (ergo) pump 5: plastic body, red end
Hello, Recently I've purchased Omnifuel II 3289 the brand new-not old stock, maybe year2020 production but not clear I'll check it from the stamp on the box later. And an included Ergopump has Black colored NRV end. I thought the recent Ergopump (with Lindal Valve) has the Red instead of the Black. I don't remember the shape of end cover, would check later. So the Ergopump with Black NRV may not mean that is the elder revision.
It seems there are several ErgoPumps with the black end cap flying around at several resellers. A few days ago I have also purchased a new ErgoPump (expecting it to be red), but also the black end cap was delivered. I opened a reclamation and the pump should have been replaced, but now the reseller told me that they again got a pump with a black end cap delivered from their distributor. :-) I thought the black end caps have longer "grip wings" and therefore don't fit into the 350 ml bottles? However, the OmniFuel stoves are getting delivered with a 600 ml bottle, so probably this is not an issue with them.
Hello, I remember only the color of the recent Ergopump as a Black NRV, as you told it would be the same as one step elder one which was having the two grip wings. Will check it in next days. Good day!
One other question: How is this fuel filter pod (made of brass) attached to the fuel hose of the pump? Is it just clamped onto the hose end, or is there any glue? I am asking, because in my case this brass has loosened from the hose. So I am now thinking if I can replace it with the filter pod from newer generation (that do not have this metal mesh anymore).
I checked mine, the newest revision of the ergopump which has the black end nrv cap, from the full package of 3289 Omnifuel II, year 2021 production. But it has the Shorter wings not the same as the elder one, seems only the color is now black instead of Red, but don't know exactly, don't care about it so I didn't compare with both in detail. Regarding the End Brass Filter part, I don't know because I don't have the Brass Meshed filter one, mine is the elder aluminum pump like yours but it has Brass filter with White filter material same as this day's. Anyway you may try to re-glue it with Epoxy. or if you could, you can fill some filter material inside upon you're fixing it, the brass-mesh is not enough to filter the micro particles. Recent primus burners do not have any shaker-jet system so the better filtering would be nicer than...
Hi. Anybody here can help me with my primus himalaya pump? I bought a replacement pump from primus but it has a different connection. Im having a difficulty inserting my fuel hose. picture attached; left is the new one Right is the old (broken one) see the difference? Now im having a difficulty inserting my fuel hose to my new replacement pump.
Edit: I am sorry, I was confused by this previous picture of the old aluminium pump. Please ignore my reply... :-( I thought you want to attach a CEJN connector into the new ErgoPump. - - - - - - - - - - Actually I think you are mixing several things up: there is absolutely no need to remove the rotatable connector out of the new ErgoPump (!). This part should always stay inside the pump - it is only getting removed in case the rubber sealing suffers some leakage (to replace the rubber sealing) the new ErgoPump is designed to screw a Lindal valve hose connector onto this brass thread of the rotatable connector, it is NOT designed to remove the rotatable connector out of the pump and plug in the old version CEJN connector instead... the big advantage of Lindal valve connectors is that they can be used with gas cartridges also. Primus does only use Lindal connectors nowadays. Unfortunately I have to tell you that your old hose connector is not compatible with the new ErgoPump connector. While the new ErgoPump has a screw-on Lindal system, the old connection type (that you have been using on your aluminium pump) was using a CEJN plug-in connector. To resolve this, you should be able to replace the complete fuel hose (which is attached to the stove) with a new version hose that has a Lindal connector instead of the old CEJN connector that you have been using before.
I did not remove anything from my new pump. It is suppose to be a warranty replacement pump from primus. I was shocked that it has a different connector with my old pump though. picture attached here is the fuel hose connector i have on my himalaya stove.
On your second picture in the previous posting (the picture where you held both ErgoPumps close to each other) it seemed that you have removed this rotatable Lindal valve connector from both pumps. The new ErgoPumps have this Lindal valve connector that you can see on the following picture (brass part on the right side). There is no need to remove this part, as you can screw on the hose directly onto this brass thread. Could you take a picture of your whole stove set? Including both pumps and the hose incl. connector? Apparently you are using the old version ErgoPump with the previous CEJN-connector I guess. It looks like that:
I actually manage to solve the problem. I changed the oring with a smaller size . Stove working fine now. Thank you very much!
A bit off topic from the o-ring thread. I cranked up my Varifuel 3278 yesterday. It's been a while. Ran amazingly strong. I've misplaced the instruction sheet and was wondering what the "on" run side & "off" other side are in reference to? These are both stamped on the top of the aluminum pump block. Merci Beaucoup
I learned when flipped to the "off" position, excess fuel in the line is burned off eliminating it from pouring out when disconnected.
Hi, I was recently in a same situation as you with my new Himalaya multifuel that arrived in a rough condition. It was leaking from every seal I could find. The pump side of the lindal valve connector came apart by gently removing the star shaped retaining washer with gasket pick, and then pulling the piston out.There is no groove for the washer so gentle brute force can be applied in order to remove it. Photo of the internals attached for those with leaky connectors and also for the curious ones since I could not find any schematics on this part before this operation.
