Peak I Apex II Hose Replacement

I don't remember removing a nut from the pump side, but then maybe I did. It's been so long ago. If it makes the job easier, then by all means... As for the old hose, I would remove the old hose and the old crimp just to get it out of the way. It's a low quality plastic tube that should be replaced at the first sign of brittleness. Since I made the repair on mine, it has remained flexible and very usable and is a big improvement over the stock tubing.

Thanks for a prompt reply. Charging my drill/cutter.

Where/what did you use for the metal braided shield?

 

had some old plumbing hose in my garage and cut the braid off of that and applied it. Works great. Doesn't matter how big the braided hose is, it will stretch to fit and then it will stay snug once clamped down.

hope that helps,

Sam, any chance to plumb in a pump of some sort, fuel line to the stove without OEM hose ends? Or give the hoseless, pumpless stove away? This is one of the stoves given to me for postage, I got the 8R going with little issues.

 

Duane,

Every once in a while a Coleman pump will come up on eBay. You might see if you can get one that way.

HJ

 

HJ, are they like MSR pumps, they'll fit other models within the brand? Coleman in this case? Not too worried, it is a cheaply built stove, but in good condition.

 

Duane:

I don't have a lot of experience with Coleman pumps to be honest, but I believe all Coleman pumps of that type will fit all Coleman bottles. I do not think that all Coleman pumps of that type will work with all Coleman stoves. For example, I'm pretty sure a Fyrestorm pump will not work with the connector for an Apex stove.

HJ

 

HJ, not really worth me spending money. I'll have to gift this I think. Never heard back from the lady I got them from. I know she was going to throw out the fuel line as it was unsafe, but I could of used the ends.

 

You could always call Coleman...

HJ

 

Hi Duane,

If there was a way to get the fuel line connectors, then that would solve most of your problems. As you can see in the photos above, the connectors are really unique. If you had at least the one that hooks up to the stove, the rest could be rigged up to other pumps, like an MSR pump or something similar.

I'll keep an eye out for a junker...

Sam, I would have to find a male fitting that would go into the MSR pump, then you have the issue of clipping it in place so it doesn't blow out. Thinking now, I just so happen to have a Whisperlite braided fuel line I only used once or twice on my Int'l years ago, would only need a fitting on the stove end after I cut the coiled generator part off. May be closer than I thought. I'm not worried, the stove keeps dust off my computer cart for now.

Thanks HJ, I could email Coleman.

 

Ok, cut off the old hose, removed brass couplings carefully (took more effort than expected)

new hose (not braided) in place

fired up the stove with some old coleman fuel, only 1/4th capacity:

lit up fine, has a yellow flame, not all blue that I remember. I guess I have to pump it some more.

Has a leak, I suspect near the bottle and pump, so I suspect the big O ring inside the fuel botle. Gonna replace that next. I thought i replaced that from the kit before, that was about 2 years back, and the stove sat idle.

Also, could be cross threading.

Do you know, where I can get that O ring, and what size is it? (Metric or Standard?) what size is it, and where can one get just one o ring of that size? Pep Boys (auto parts store) has a whole kit of O rings... maybe I'll try a auto machine shop.

cheers

 

You could try Pep Boys they should be able to match you up with a good Nitrile or Viton O-ring. There's also Coleman's website and Harbor Freight, both of which sell both Nitrile and Viton O-rings. The Viton ones are a little more durable. Anyway, a whole kit of O-rings at Harbor Frieght costs between $9 to $12 USD.

Hope that helps.

I know this thread is way old... but I bought an Apex II off of eBay. The fuel line leaks at the pump, so I'm wondering if it's the line or the pump itself... I can see fuel slowly seeping out of where the hose connects to the pump. The one picture I didn't see in this thread is the pump after the hose was removed... is there a brass fitting in the pump, and if so is it permanently mounted? I assume you removed the hose by cutting a groove with the Dremel for the entire length of the crimped fitting, on opposite sides, and then just peeled it away?

 

Well, upon closer inspection in daylight, I can see that the pump body itself is cracked where the hose joins it... and that is the source of the fuel leak. I think having the hose attached puts strain on this and it will eventually crack. I have a new pump but for the Fyrestorm on the way, will have to make up a new hose with the Apex connector and a connector back to the Fyrestorm pump.

 

@John Clifford,

It has been a few years but I think both pumps use the same threading on the pump. You should be able to unscrew the Fyrestorm fitting and screw on the apex fuel line, that is if you can get it off. I have been successful in the past converting apex's to use the Fyrestorm fuel line, regulator, and inverted canister adapter, but be aware the Fyrestrom pumps are made out of the same crappy plastic as the apex's and they will eventually crack as well.

Mike

 

Yep, my new Fyrestorm pump came in and it was cracked in the same place! Old Coleman Parts stood behind their pumps... the owner called me after my email, was going to send me a replacement pump from his inventory that came new from a former service center, but they were/are all cracked in the same place!

I've disassembled the hose and fitting from the two pumps I have, I also bought a $15 butane stove (BRS?) off of eBay and a Primus ETA multi-fuel kit that provides a pump, fuel bottle, etc. The butane canister fitting on the BRS hose attaches to the Primus pump, and now trying to figure out how to get it to hook up to the Apex... wondering if I could just pick up a female-to-female adapter that would let me attach the BRS hose to the Apex hose and then I'd be done with it.

 

I went backpacking a few days ago with my 17 year old son. The last time I went backpacking was a few weeks before I me my now wife in 2000. So I was going to fire up my Apex II to test it out and saw it leaking at the hose, so I resorted to my old Coleman 400 which worked fine.

So as I often do, search the Internet and found this site and so appreciative of it as it set me in the right direction. I've Dremelded old off the barbed fittings, and am ready to buy some 3/16" hose. I can't find any braided hose, but not worried about it blowing up.

 

Welcome to CCS @Reid

 

I got it running! There was a bit of a flair up coming from underneath the burner, which is a little scary living in California, but didn't find a leak, and doused it a few times with water, and now it seems to be behaving.

It there an optimal length for the hose? I just used the 24" hose that I got from the store. The stove pulses, so I suspect that's a pressure issue from the long hose. The original hose was too short, as think I'd like to have a 14" would be ideal. I couldn't find braided hose so just have rubber. I'm not worried about the hose overheating since it doesn't get hot and was designed for gas anyhow.

Thanks,

Reid
