How to install fuel sock

[ducatijohn]

The garbage that's in pump gas can and will eventually clog up the tiny injectors in our small bore bikes. That's why most KTM riders either use a Golan fuel filter or a fuel sock. I looked at the Golan filter but didn't want to cut the high pressure fuel line for installation, plus space was an issue under the tank as everyone knows.
I found this: www.split-stream.com
I took a chance an ordered a fuel filter sock made for a 2013 KTM with screw in cap. It was a snug fit but it worked! I then removed the gasket from the Husky gas cap, made a couple of new gaskets, inserted them into the gas cap and now I have less worry about junk in the tank.
The photos below shows the fuel sock, gas cap, gaskets and sock inserted in the tank. The web site states that injector nozzles are 50 to 60 microns in diameter. The fuel sock openings are 25 microns in diameter so now I can ride worry free. Don't forget to take out the fuel sock periodically and back flush the crud out.

what did you make the gasket out of?

I did see Twin Air makes fuel socks also.

I tried a gasket out of inner tube material but it was too flimsy and thin. I had a piece of medium durometer vinyl and cut out 2 pieces. You can find rubber sheet at Home Depot which will also work. Good luck!

Hey have you heard of or found one that actually just fits without playing with it? Thanks

You don't want to use a Golan filter anyway. The stainless steel element in their filters shatters around the edges and clogs the injectors. This cost us our Glen Helen 24hr race last year. We have a brand new fuel system in the works, should be out soon.

Nice Bultaco, oh and good idea on the socky!

Used

I use these and they are great perfect fit and require no alterations to fuel cap.

them as well. Happy with it.

Ordered one of the profills. First line of defense, especially if filling from a can on a windy day in the woods.

Profill arrived in 9 days. Fits the tank/cap nicely as is. Press fit it is snug and cap screws on easily. Seems well made.... Happy to say it does not slow down filling as the docs say it could, though I pump slow to reduce splashing. To that end sort of works as an anti splash screen instead of hitting the front of the tank and coming right back at you.

I ordered one too, but so far after 12 days it has not shown up yet. So with Monday being a Holiday the earliest it will be here would be 14 days. Sometimes our port of entries slow things down a bit.

Interesting. I will go with a profill, first off because I hate the splash of gasoline on the red pipe when filling her up , and second if it stops dirt and protects pump and injectors, these will be $30 well spent

I got one on my TE511. It is fantastic and 0 issues so far. Still looks pretty clean tho :\

Ok my Profile unit came in today. It is a very tight fit! What I had to do to get it in was pull the sock back through the plastic opening to the out side of the tank while installing it so the sock itself would not be
pinched between the wire and the tank. Then I just pushed the sock back inside the tank. I think it's going to work fine.

Ordered one a few days ago . I am more concerned about the anti splash thing because 98 gasoline "seems" clean here in France (I would not be as affirmative with diesel )
