In Tank Fuel Filter - Manky
« on: October 03, 2018, 03:19:14 pm »
Hey guys,

After seeing the state of Dennis' fuel filter, I thought it a good idea to change mine.

Good thing I did !!!!

Manky .... after only 5000km's. Not really sure what this is ... anyone have any clues ?

Geez, that is dirty! No idea, but it looks like very fine particles? I hope the much anticipated guglatech filters will help prevent this...

It seems like its carbon ... I have plenty of bikes and I've not seen anything like this in a fuel filter.

I don't think that is contamination in the fuel, like Mark says it looks and feels like very fine carbon. It's very fine and feels slippery almost like graphite. I suspect possible pump failure.

I believe it is carbon graphite from the pump motor brushes. Mine looked similar but not as bad after about 3500km. I have eliminated this filter entirely from the tank and fitted a serviceable external Golan filter.

on my 1190 and now the 1290, the in-tank fuel filter was clogged, each time at around 15 000km
I have now installed a googlatech pre-filter on my tank - hope that will be sorted now.....
below are my 1290 filters when the bike started losing power above 5000RPM

I run Gugla filler filters and the Golan external one. Feel covered at present. I still believe many (if not most) fuel pumps that go belly up are due to poor and clogged filters.

Every bloody KTM I've owned also gave me problems with this exact Tea Bag Fuel Filter, both my 990 and 990R and the 1190R.
I'm convinced either we have the worst fuel in the world, or KTM fuel filters are the worst in the world. Ha ha.

On my 990 I fitted the long range tanks and placed an in-line fuel filter between the 2 tanks.

For day to day riding I only fill up the one tank so that all fuel goes via the prefilter first. Will see if it makes a difference or not in the long run.

After 2800km (2020 model). It didn't have the in-line filter installed at the quick disconnect......

Need some opinions. Got this filter to replace the in-tank filter with a service-able external filter. The guy at this shop said it will work with fuel injected bikes.

It just does not matter how many times one says to fellow Euro bike owners to simply cut out the in-tank filter an fit a cheap Opel filter on the outside..........no one listens.

You need only fit an external GUD E-13 filter, and you are sorted for life. Really, these filters do 50 000 kms on a 2lt 4cylinder car, so your puny 700cc single is not going to dent it much.

But if you want to pay a lot for fancy footwork. it's your money...... :ricky:

oh, and the fun part is, I am sure I bought the bike with a prefilter already installed.

Gud E13 is the final answer plus Guglatech bag filters in both tanks.

The issue isn't dirty fuel....

The issue is either the lining in the plastic tank (unlikely) or the fuel pump brushes from new.

so you say the cause could be a inferior fuel pump. My bike is still relatively new. I would be most unhappy if I had to replace the fuel pump now....
