Guglatech Filter or Mr Funnel(no joke)f1

[7800]

Hi Guys

I am looking at fuel tank filter. Has anyone used either the Guglatech "fuel neck prefilter"(seems very expensive for what it is) or the Mr Funnel f1(cheaper but is more messing around)

Thanks

I know a V-Stromer who used a Gulgatech (is that the Italian one?) and it caught a whole lot of crap before it got to the fuel pump in Asia.
There are other fuel socks around.
Was it that expensive - 80eu or smth?
I suppose you could MYO - the fabric looks familiar.
Mr Funnel would be a faff on a bike, IMO.

I have the Guglatech neck filter on my 790 Adv. It seems like a pretty effective filter but does make filling rather slow. Firstly because the fuel has to flow through the filter under gravity. Secondly, as you fill the tank the displaced air comes out of the filler cap, but now has to flow out through the wet filter. This means as you get to the top you get a lot of frothing which slows the filling process even more. It's a hassle but for the benefit of knowing my fuel pump is protected going through the Stans I'll put up with it.

Fuel pump problems are common in that part of the world and there are plenty of stories of people burning them out, either because the upstream filter blocks so they run dry, or else because the downstream filter between the pump and injectors blocks causing the pump to run excessively high pressures. Either way avoiding dust in the pump is essential.

For this reason I've also got (but haven't yet fitted) the Guglatech filter that goes in the tank and covers the pump. Belt and braces!

Thanks guys I think that Guglatech is the way forward, less faf.

I got a Guglatech Mazinga for my 2014 KTM690 Enduro, brilliant idea but unfortunately it won't fit, seems that the tolerance in the opening of the tank is too tight to accept the fuel pump casing with the Mazinga over the top.
The pump itself is a tight fit so I'll have to get the file out next time I have the tank opened.
A simple but sensible bit of kit.

I've also removed the in tank filter and fitted a Golan re-usable external and will be using a FloTool F1NC meantime because it's also very simple and it works!

I did try the ProFilter tank neck sock but it wasn't for me.

hi,

I have been using them for all my trips since 2015, transafrica round around, more than 90.000 km and never an issue, I have been using all generations on my KTM 990 never suffered from fuel filter or pump issues, I would never drive any bike without, shame they haven't finished the air filter!!

Mr Funnel works around 150 microns last time I checked, Guglatech made a video comparing all filters brands and models showing how effective they are ... plenty of adventurers use them happily, nothing compares !

get them

ciao

Tomkat,
Can I ask you a favor? Can you do a little 30 second video of filling up? I'm looking at getting one for my Mongolia-California trip on my KTM 790AdvR and you are the only one of even heard that has one on a 790. As u know, the tank is a little bit different.
Also, I'd like to post up your vid on Advrider.com if thats ok...?

I’m riding across to Bangkok from April 2020 from U.K. and intend to fit the neck filter....do you think it necessary to fit the filter over the pump too ?

I'm thinking about the same. Fiter for filler neck and pump.
Its recommend by Gugglatech to use both, but I'm doubt. In my opinion its sufficient to only use the filter for the fuel pump. I don't like to have difficulties while refueling due to the filler neck filter (its a KTM 790 ADV R)

I've also tried a Profilter tank filler filter on my 690 Enduro and found it to be frustratingly slow to fill so I'm going to somehow make the pump ' Mazinga cover ' work as a fit and forget item.
Also have a look at the Golan 10 micron washable filter with the intention of fitting it between the tank and injector. Expensive but it has almost limitless use.

Golan Super Mini Filter RRP 383

Sorry, can't comment on the 790.

[mks916]

is the Profilter tank filler filter also from Guglatech or a different product?

Thanks

[Riel]

Different, Profill is from Australia,

Guglatech is from Italy

Thanks Riel.

The guys at Guglatech have been incredibly helpful, seems that the opening to my 690 Enduro tank is slightly tight so perhaps a manufacturing anomaly, so they are making up a one off 2 layer Mazinga ( instead of the usual 3 layers ) for me to try.
If this works out I'll then sell the unused original. I can use Mr Funnel at the pump and that will remove any larger debris as well as water, the Mazinga will protect the pump itself from sucking in finer particles and the 10 micron Golan should help stop anything else getting through to the injector...I carry a spare injector anyway so most scenarios are covered !

I have the Guglatech filler filter on my 790R and at first I thought it was a bit slow but after chatting with the very helpful people at Guglatech I re positioned the filter inside the tank and now it actually is not bad at all.

You still need to be careful especially when its near full.

I have the pump filter also but haven't got around to installing it just yet.

You may think its a bit expensive but imagine a busted fuel pump in the middle of kazakmoliastan....

Not everytime you have a helping hand.. For tanking 250l Diesel (280L capacity), it is quite a lot of work.

We did you a MrFunnel F15C Filter. There is a link to a good storage bag (unfortunately I did`nt had it with me).

It is hard to find the Micron-Rate, but here it is labled as 74 microns.

I did just did use it in africa - in south america I did just fill up in bigger city`s. Where there a BMW X6 is refilling - there the fuel seems to be ok It was a mess to handle such an external device in any way...
