Peak I Apex II Hose Replacement

I've settled on the Magna Clips. They look pretty cool and will go nice with the metal braiding. Hopefully I get those soon.

Morning, Sam,

Very nice job, Sir! This Apex II is stying, now, and looks wonderful! I look forward to seeing the new clamps. Take care, and God Bless!

Every Good Wish,
Doc

 

If you're feeling flush, go to Napa auto parts and have them build a new armored hose, with swaged fittings!

 

Sam as I mentioned earlier the magna clamps look good.



Hey Steve, does NAPA really do crimped hose fittings? Thought they just sold parts?

Sam do post when you get the magna clamps fitted.

Mine does, fuel lines, brake lines, hydraulic lines, chow lines...
They also do engine overhauls, valve jobs, some tranny work, and also sell parts for my 1958 Ford 861 tractor !
Did I mention they also sell auto parts???

 

Thanks for the picture of the pump. I never thought of looking on the bottle. Easy repair now

 

Ha! Made you look!

Clamps are almost here. I'll post pictures of fitted clamps soon!

I ordered the wrong size of Magna clamps.

I was a little put off by my mistake, but as I played with the hose and some brass tubing, I figured all I needed to do was cut a couple of pieces, which measured 7/16" I.D. and at 3/4" in length. These brass tubes fit snug around the metal braid and fuel line core. It made for a tight fit around the brass pump fitting and the stove connector as well. I then grabbed a pair of locking pliers, which fit completely around the tubing and crimped the tubing making sure it didn't become out of round. A pair of locking pliers with rounded jaws works really great for this. I also made sure that all of the slack in the metal braid was pulled out before I cut the excess off. If you can tell, the metal braid is snug around the fuel line with no sagging.

It's a little rough, but I found that it worked quite well and was able to make a good tight fit. I made sure it passed a strong pressure test by pumping the bottle up with 75 strokes and let it pressurize the fuel line. I let it sit for a while to see if there were any leaks - there were none. I finally connected it to the stove and fired it up.

Hope this helps,
sam


Finished product. Nice and long braided line. Looks OK.





Lighting it up! These stoves seem to give off a nice blue flame.

 

Morning, Sam,

Well done!! I really like the extra long fuel line, too. Very convenient, and quite workable. I find that those burners back into a cook pot very well, and usually wrap mine in some thin rag, to protect the pot. Again, great job, Sir, and well done! Take care, and God Bless!

Every Good Wish,
Doc

 

realy great work

 

Added pictures of this stove and other Apex stoves in the SRG: Peak 1 Apex & Apex II, '93, '99, '02

 

Good Idea.
The press fittings is made by using water tube, squesed between 2 steel bars with a 1/2 hole in each.

It is a few things to consider while doing this.
the valve on the quick coupling is sensitive to the hose clamping.
The inner volume of the tube increases, and makes the prehating more complex, you may risk to get too much fuel, and get high flames.

Min is too long!




My apologies to the Coleman engineers for my suspicion about their completely stupidities conserning later models having big problems with flareups in the start. It may have been designed right, and modified on demand from "sales" just to get longer tubes, and safer (more complex) couplings.

But sorry, my conclusion is: Coleman has lost somthing on their way, and if thay dont get it back

Here is the tool I used, Dont know what you call it, but simular ar used for forming brake lines, this one I gat in the scrap

Now, I have shortened the hose to aboute regular length, and it works great in the start too.

How does the long hosed stove work for you Sam?

The long hose works great on my silver Apex! It's a really nice setup. I like that it is nice a far away from the stove. I was a bit nervous with the shorter original hose. Anyway, I tried it on my copper Apex and got a pulsing flame and no problems on startup (Coleman Fuel in everything). I thought it was the generator so I put a new one on, and still got pulsing. I finally figured what you figured out: too much fuel, and turned the knob down and that stopped the pulsing. I guess the larger I.D. hose was pushing too much fuel into the generator or something.

By the way, I really like your tool. Looks like the perfect setup. Could you maybe show the tool in action?

Thanks for sharing,
sam

 

Sam, I was given a Apex II stove, but no pump was sent along. I emailed the lady who sent it to me, but have not heard back. I see I would also need the stove end connecter off the hose she said she was going to throw out as it was unsafe. I did get an 8R out of it also, just for the shipping charges but I sent her $20 anyway.

 

That stove is pretty useless without the fuel connector at the end of the hose and the pump. Unless you have another Apex II that needs the parts, that's probably going to sit for a while until you find replacement parts or sell it.

A chock for the truck?

 

LOL! Yeah, that will keep the stove from running down the hill!!!

Great Website and great descriptions, Thanks.

I too have a Peak 1 Apex II stove, with a leaking hose and am getting ready for a hose replacement.

Bought the 3/16 ID fuel injector hose.

I plan to use my drill with a grinder to cut off the crimp end on the stove end first and retrieve the nipple, and use hose clamps.

On the pump end, there is a nut attaching the hose to the pump. Should I unscrew that before cutting the crimp off and removing the old hose, or should I work with the old hose attached to the pump?

thanks

 

If there were any concerns about the stove being too hot for the new fuel hose, I wonder if some kind of radiation shield/heat reflector could be rigged up.

Here is a photo of my MSR Whisperlite. Note how the aluminum heat reflector is protecting the fabric covered fuel line:
