X Air Hawk fuel tank 'shedding' particles into fuel


 

Hello everyone,

I have read that the x air Hanuman comes with two different types/colours of fuel tanks - one that is capable of running avgas and MoGas with ethanol (yellow-ish tan coloured tank), while the other white-clear tank only accepts avgas. Please correct me if I'm wrong.

Anyway, I have the yellow-tan tank that can accept both grades if fuel. I don't know if the above information is irrelevant, but after 150hrs of fuel tank use (14yrs since new), I am noticing flakes from the material of the fuel tank.

The only fuel that has been run in this plane is 100LL.?

I notice the fuel filter trapping these particles but why is this happening ?

My XAir tank was whitish, I only used 100 LL , and I never had any debris issues in the Gascolator.?

Yes sir - you are bang on.

So what do I do??

Replacing the tank is out of the question for me.

Do I simply and constantly clean the fuel filter every 10hours??

It honestly depends on the fuel and the additives that are used locally when it is produced.....?? Fuel is not fuel any more..........

I have seen some excessive fuel tanks deteriorate in as little as 12 months from ethanol car fuel. If you have debris inside the fuel tank that is flaking off the best thing to do is drain the fuel tanks, put about 3 feet of chain in the fuel tank and Shake like crazy !?? the chain will break off any of the exposed fibres, you then need to flush the fuel tank as many times as you can to remove the debris and you should be good for another year or two.

Because the debris is normally fibreglass it is almost impossible to see in the fuel filter when it is wet Because it is completely translucent (just like Glass)?? When it dries out however it looks white like rabbit fur or something similar so if you just looking your fuel Filter if it has a glass Shield you may not see that your fuel filter is 90% clogged. It is amazing when you pull the fuel filter apart and the fuel starts to evaporate it looks like all of these fibres are actually growing on the fuel filter as they dry out and become visible.

Very interesting and valuable information, as usual Michael.

I will keep my eye out.

I noticed my gascolator valve leaking today.

My tank has been completely dry for 3 months. I just put fresh fuel in it and I thought to open the gascolator. Sure enough, it started leaking. Now I understand what those white rabbit like hair particles were.

I did notice these particles in the fuel filter before but now I will clean it more often.

Many thanks!

Wouldn’t it be safest just to use only 100 all fuel only, after you have thoroughly cleaned your tank? ??

Mogas has to be carefully sampled every time to ensure No ethanol, which is the problem for fibreglass tanks. ??

While 100 LL can lead to plug fouling if proper mixture management is not employed, ?I never had that problem even with my Jabiru engine that had no manual mixture control. ?The Jabiru engine manual even recommends using ?100 LL for good engine performance and cooling. ? My AME highly recommends using AVgas. ? ? He also says many owners who tout the benefit of their Mogas STC don’t really realize what the STC means. ? You don’t just throw in Mogas and take off. ?The STC requires specific sampling technique prior to a flight for compliance. ? The “devil is in the details “. ??

Not everyone has a Jabiru engine fitted,?? The Rotax prefers car fuel.

Either way, the fuel tank in the X-Air aircraft is just vinyl ester resins and they are affected eventually by fuels of any description, especially when you have to make it as light and thin as possible.

Best for any fuel still seems to be polyethylene but its heavy.... ? Look at how many outboard motor fuel tanks there are around the world that are left outside day and night, in some and rain and use all sorts of fuels and yet they are still working after 30 years, can't do that with a Fiberglass fuel tank.

My light yellow tanks started blistering so I took them out fabricated aluminum tanks and solve my problem.

When it dries out however it looks white like rabbit fur or something similar so if you just looking your fuel Filter if it has a glass Shield you may not see that your fuel filter is 90% clogged. It is amazing when you pull the fuel filter apart and the fuel starts to evaporate it looks like all of these fibres are actually growing on the fuel filter as they dry out and become visible.

Hello everyone,

I have read that the x air Hanuman comes with two different types/colours of fuel tanks - one that is capable of running avgas and MoGas with ethanol (yellow-ish tan coloured tank), while the other white-clear tank only accepts avgas. Please correct me if I'm wrong.???? I have not heard this ???

Anyway, I have the yellow-tan tank that can accept both grades if fuel. I don't know if the above information is irrelevant, but after 150hrs of fuel tank use (14yrs since new), I am noticing flakes from the material of the fuel tank.

The only fuel that has been run in this plane is 100LL.?

I notice the fuel filter trapping these particles but why is this happening ????? The resin is leaching (being eaten) away by the fuel additives from the fibreglass and the fibres are breaking off, this is your "debris" most probaby

How involved is it to remove my oem fuel tank and fully clean it out?

do i just undo the velcro at the bottom of the fuselage to get to all fastening straps, or will it require more dismantling?

My light yellow tanks started blistering so I took them out fabricated aluminum tanks and solve my problem.

Very interesting and valuable information, as usual Michael.

I will keep my eye out.

I noticed my gascolator valve leaking today.

My tank has been completely dry for 3 months. I just put fresh fuel in it and I thought to open the gascolator. Sure enough, it started leaking. Now I understand what those white rabbit like hair particles were.

I did notice these particles in the fuel filter before but now I will clean it more often.

Many thanks!

It will probably take you about one hour to remove everything and have the tanks lying on the ground

Agreed, it is nothing to do with the engine it is to do with fibreglass, vinyl ester resins, epoxy resins and their weaknesses to current aviation and/or car fuels.

This issue is simply, fuels or additives in fuels leach into the resins and dissolve them therefore leaving exposed fibres from the fibreglass which eventually get broken off from the fuel sloshing around and then they end up in the fuel lines and the fuel filters eventually causing fuel supply issues, engine stoppages etc.

It is only the bottom end of aviation that uses fibreglass fuel tanks, every other industry knows their weaknesses and has moved on to other products. Most cars 25 years ago used steal for their fuel tanks but almost unanimously they have all now change to polyethylene because it does not rust, it is much superior in an accident and it does not get affected by the fuels we are currently using.

The problem in the aviation industry is fibreglass is easy to manufacture and fairly cheap, you can make round shapes very easily like the corners of the fuel tank, it does not rust and most importantly for us, it is lightweight, the downside is it is not durable when it comes to different fuels.

Polyethylene is used for aviation fuel tanks in some aircraft but it is about 10 times the weight.....??

There are a number of "sloshing compounds" that can be used which you mix up and pour into a fibreglass fuel tank and then turn it around in all directions so that the surfaces are coated and when it dries it provides a barrier between the fuel and the fibreglass.

The problem with these is that they are not always successful in bonding with the fibreglass material even when you use the proper primer and it is because the inside of the fuel tank is nice and smooth because this is the inside of the mould when it is made and the material doesn't stick so well....

Something else which is worth looking at is a fuel bladder but these are also heavy and are quite expensive....

The current alternative seems to be, remove the fuel tanks once every 12 months, throw a chain inside and move it around breaking off all the fibres and put the fuel tank back into service.? Clean fuel system regularly, use a good quality fuel filter that can capture the fibres and the problems are solved, or mitigated at least.

Hello again Gents,

I cannot find any information regarding the GPH (gallons per hour) or PSI min. & max. for our electric fuel pumps.

After a frustrating 20 minutes, I was able to remove the fiberglass belly pan of the X Air H. I am glad I did this because the previous owner didnt install the bypass fuel line section with a 1-way check valve! Why do you think he did not do this? He built the airplane pretty well with upgraded wiring and other parts, but maybe because he felt more connections means greater potential for leaks?

Moreover, I notice I have a Facet Cube fuel pump - model # 40105. The specs on the Cube 40105 are: 30GPH, 3.0 min PSI and 4.5 max PSI.

Is this correct? I feel like I should replace the electric pump, just in case. Here is my reasoning: the previous owner didnt even install the supplied Facet fuel filter into the Facet Cube! Why did he not do this as well?

After the fuel tank, I do have a Dorman 55240 glass fuel filter, which is great, but because of my paranoia with the fiberglass/resin and organic particles in my 100LL fuel that is currently in the tank, I wont be surprised if there are some fine particles trapped within my Facet Cube - engine & plane currently at 160hours.?

I cant seem to find any info regarding how much min. and max. and GPH my 22A2895 Jabiru 2200 (160hrs) calls for, in the event my Jabiru mechanical fuel pump fails.


 

The jabiru 2200 uses a bing 54 carb. The nominal pressure for them is 1-4 psi. They need to be fed, but anything over 4 psi can cause the carb to flood.
he probably didn’t install the facet filter because they aren’t serviceable and was relying on the main filter.
The bypass isn’t always a well known thing and more of a work around to avoid failure. Theoretically the facet pump should allow flow through. Just sucks to find out that one time it won’t or that it’s causing a bit to much restriction when it’s not running.

Hello again Gents,

I cannot find any information regarding the GPH (gallons per hour) or PSI min. & max. for our electric fuel pumps.???? this will be in the requirements from the engine manufacturer, it will stipulate a minimum and a maximum psi for the fuel supply so this is nothing to do with the aircraft but is unique to individual engines

I am glad I did this because the previous owner didnt install the bypass fuel line section with a 1-way check valve! Why do you think he did not do this? ignorance or trying to keep costs as low as possible???

Moreover, I notice I have a Facet Cube fuel pump - model # 40105. The specs on the Cube 40105 are: 30GPH, 3.0 min PSI and 4.5 max PSI.????? a quick Google search led me to the Jabiru manufacturers website where it states the maximum pressure should be 3 psi please this is just a Google search please look at the manufacturers manual and specifications for their product

Is this correct? I feel like I should replace the electric pump, just in case. Here is my reasoning: the previous owner didnt even install the supplied Facet fuel filter into the Facet Cube! Why did he not do this as well????? because of the well-known problems with clogging of this filter. Most people do not use this filter and instead install a proper filter upstream

It is pretty simple I just went to the Jabiru website and downloaded the installation? manual for the 4 cylinder and 6 cylinder engines and they are saying minimum 2 psi and maximum 5 psi. This comes directly from the manual at the link below and I would not use anything but the engine manufacturers specifications

ok perfect - so my current 3-4.5 psi set up works - great to know.

I'll just replace the current pump with the exact make and model, or if there are stock shortages near my location, ill find something with a max of 4.5psi
