Coleman Apex II model 445A700 pump assembly

Hi All,

Just stumbled upon this forum and signed up. I did a quick search, but have not found an answer yet.

I have an Apex II that I bought a long time ago and have been happily using.

I think the pump assembly needs to be replaced - the plastic housing where the fuel line exits seems to have split. I have a leak that may be the o ring on the shut off valve, or the split, not sure which.

Any suggestions?

Thank you in advance for your help!

Welcome to CCS Rich!

I dismantled the pump - and some more besides - in THIS post.




Post photos if you can of the split/crack in the pump, which might well make it a write-off, sadly.

Hi John,

Here is a picture:



I am afraid it may be a bust. The leaking through the shut off valve stopped with a new o ring installed.

I was thinking about JB Weld...perhaps filling the crack with it or another epoxy might work...but I kinda doubt it.

Any other pump assemblies you know of that have been successfully adapted to use on this stove? I saw in the post you referenced that you used a primus pump assembly, though it seems after you had a warm stove.

Welcome to CSS,

I have had those pumps crack from age just sitting in a box. I'd swear they were good one year and then when I check them out the next year I'd find another one cracked in the exact same spot as yours. Those pumps are unique to the Apex line with their quick disconnect feature. As long as yours does not leak from the crack you could probably epoxy the crack and it would be fine. If you would like to happily continue using your apex and don't trust the epoxy or if you'd like a spare pump just pm me by scrolling the mouse over your name in the upper right corner and start a conversation.

Unfortunately it is leading in the cracked area. The JB weld is probably not a workable one with a leak.

I will start a conversation with you about a pump

 

Oops...nevermind...PBKAU

Hi,

There is no good way to repair these plastic Coleman pumps.
It looks like the fuel hose is in pretty good shape.
There are a couple ways to fix your stove so it will work again without any leaks.

If you take a look at your picture you will see the crack in the plastic. You can see where the brass ends and the stainless steel braid starts. Wrap some electrical tape around where the stainless steel braid starts and use a large pair of wire cutters or a cable cutter. The reason for the tape is to keep the stainless steel braid from unraveling. Next you will need to get a BRS fuel hose with control valve and you will need to connect the two different hoses and what works best is this type of micro or mini connector. You will need to use a reducer 3/16" to 1/8". You can find these reducers at
https://www.mettleair.com/store/bra...reducer-nickel-plated-single-barb-design.html
You will also need some clamps to secure the connections. The clamps I use are the single ear made by Oetiker and these can be found on Amazon.


This sounds much harder then it is and the conversion is pretty easy to do.

Now the easier of the two is the remove the end which connects to the stove and place it into the fuel hose of the BRS fuel hose with valve. You will still need a clamp to secure the connection but this option is much easier. Your stove will run like new again.


I hope this helps a little.
If you need any help send me a PT.

Cheers,
Norman

I've already sent him a new pump.

Mike

 

@HunterStovie , any chance you have another? Mine is cracked in the same place as Richard's was and I haven't been able to find a replacement and I'd rather not buy a different stove. If not, @teckguy_58 I'd love some additional info on your fix.

Thank you all in advance
Chris

Sorry, but I currently have more stoves than pumps, and parts/stoves for the conversions using the Apollo/Pulstar have dried up. Right now I don't have another solution for you.

Mike

 

@cjohns716

I may have a new pump, but I need to check my stash of Coleman parts. If I do I will let you know. I'm not at home and won't be there until Friday or Saturday.

Cheers,
Norman

 

@teckguy_58 much appreciated. Let me know if you find one!

 

@teckguy_58 any luck?

Hi Chris,

Good new is I found a new unused pump and it is attached to a new unused fuel canister.
I would recommend replacing the O-Ring on the pump. Right now there are no leaks but that can and will change with use. Yep you don't want fuel to start leaking while you are running the stove.
Granted you may not want another fuel bottle, but the pump and fuel bottle come as a pair. These are free, but I do ask you pay for the shipping. I do hope this is agreeable for you.
PT me your address and if you agree to pay the shipping I will get the pair boxed up to send your way.

Cheers,
Norman

 

@teckguy_58 I sent you a message a few days ago (at least I think I did). If you didn't receive it, let me know!

Thanks again!

 

@cjohns716

I did get the message but my work called so off to work I went.
The pump and fuel canister will come via USPS Priority Medium Box with tracking #.

Cheers

Hi Chris,

The package is on it's way you.

Remember to change the large O-Ring on the pump.

Cheers,
Norman

 

There are several Apex threads on the Coleman Collector's Forum. I don't have an Apex so didn't read through them but several seem to be dealing with the problem discussed here. might be worth a look. just use the search feature keyword Apex

 

You can still get the stove maint kit from coleman here.

Mike

 

Is there any possibility that you have another pump assembly for the Apex or perhaps know where I can find one?
