Desert Fox fuel cells. yay or nay?
« on: June 10, 2019, 05:59:36 pm »
How long will this kind of fuel cell last before self destructing and leaking? Is it worth it?

Don't overfill and they last forever.

Stick with 4,5 litres.

I've busted a few and it's always when I've gone 5l or more

Otherwise they're the bollocks

I've heard about cases where the bladder swells and the cap doesn't, which leads to a situation where you might not be able to get the cap off, or when you eventually get it off you can't get it screwed back on...?

Works well, dont overfill and be careful when filling to not damage the liner inside with the petrol pump nozzle

All of the above mentioned.

I used mine on a couple of trips and I'm very happy with it

I've had a 5L one for 3+ years and it is still okay. Didn't know about the overfilling issues so have always asked for 5L at the petrol station.

Surely the manufacturers must have considered the 5L as accurate information otherwise it is false to say 5L when it can only take 4.5L. :xxbah:

5L fits in mine without any effort and it doesn't look like it is about to pop. Can definitely see how a few hours in the sun will change that. Even the hard plastic storage can go roundish from pressure after a few hours so only filling it with 4.5L does make a lot of sense now that I think about it.

Unfortunately I had a very bad experience with mine.
Fortunately thanks to the vendor got my money back but no real answers to the problem of the screw cap not sealing.
Back to plastic coldrink bottles. Never a problem.

@cracklin


I’ll let BikeGear respond, but in short, a FEW caps, all two-parts caps, had the inner ‘bung part’ not seated all the way home, this made screwing the cap down difficult (or not possible), we ran some checks at the time, found one or two had displaced, rest were all fine, etc.  we have probably sold around 600 or so, had very few comebacks, but Robin did have a problematic cap, and we sorted him.


Cheers

When fill it and put the cap on make sure that you let all the air out first, otherwise the air heats up and creates pressure which in turn forces the fuel out of the cap.

I have used them extensively and had no problems.

Its a great product.

A bit of  a background to the development of these cells.

They were developed explicitly as a lightweight compact means of carrying fuel on a bike.

Over the years it has been refined from:

1. Initially a tri composite layer of 3 specially formulated plastics ( 2 fused and one "loose"l

Refrences of damaging the inner relate to this first generation.

This model also had a mechanical seal in the cap that we found over time could be compromised with high ethanol fuels.

2. Subsequent to this the formulation of the cell was revised to a fused tricomposite layer that can also withstand high content ethanol mixtures.  We have tested this with ethanol assays of 99%.

Although this may not that relevant here it is for our overseas clients.

We also revised the cap by removing the mechanical seal and replacing it with a bung.

This bung is manually inserted at production and if not inserted all the way into the cap way it may account for a cap not sealing as it should.

It merely requires pushing the bung into the cap which is a simple exercise.

The instances of this are very much in the minority and we now check the caps before shipping.

Issues of damaging the inner are also now a thing of the past

Another revision of the 5l unit is that it can now take 6L with the new tricompsite formulation. 

Having said this when handling a hydrocarbon such as petrol one needs to be mindful of its expansion  coefficient when exposed to heat.

It WILL expand considerably. We have taken this expansion into consideration when formulating the cell however a user should never:

- Overfill beyond the recommended capacity
- never over tighten the cap- it only has to be hand tight just beyond seating.

We mention this in the instructions.

I have personally used my cell over long trips of many months in temperatures ranging from -5C (Himalayas ,  Parmier etc) to over 50 C in the deserts(Mongolia , Iran) and can attest to its durability.

Some riders however  may prefer a harder canister setup which does have its own ceavats such as cost, weight and volume.

Considering that in the main the call for extra fuel remains the exception rather than the norm we believe there is room for a more compact , economical alternative to cumbersome jerry cans.

There are many many overlanders who are using these cells around the world and we would hope that their faith in the product has some merit.

It's simply the most compact and convenient way to carry extra fuel. When not in use it takes no space and folds into a small easily strapped roll.

So simple to fill it and ride about 100km. Fill the bike and stash the bag.

Ours is pretty exposed considering the way and where we strap it on the bikes, and across 3 bikes we've not had a single problem.  Well my one strap chafed through on my handguard bracket, but that was my fault.  Trust it on all my remote trips.

Hi Damaraland,

What brand are those bags on the front fender and where did you buy them? Giant Loop makes quite a nice one, but it is rather expensive.

Thanks
