Fuel filter?

[BWC]

Anyone know if the bike has one? Checked the parts list and shop manual and don't see one listed.
Please tell me its not an integral part of the fuel pump ???
Had a bad experience on my ride to Inuvik last year on the Vee and ended up doing the external fuel mod upon my return.
In a lot of northern areas you have the choice of regular,regular or regular.

Yep it's a integral part of the fuel pump, as it is on almost all fuel-injected bikes that I have seen .

What is the concern with fuel grade in regards to the filter? If the filter gets plugged, you can normally 'backflush' the filter somewhat although I cannot recall anyone having to do that, unless they mistakenly fill their tank with rust or sludge :exclaim:

Our pump looks very similar to this one....

Fuel octane ratings have absolutely zero impact on fuel quality so just because you put regular in it means nothing. There are no different detergents from one grade to the other. It is an anti-knock/octane difference only.

Yes,needs a bit of clarification. So the filters in the fuel pump as usual. Is it replaceable separate from the pump?
The regular fuel reference was more related to the fact that a lot of the stations up north have kind of questionable pumps,rusty looking external filters on the pumps and generally make you wonder as to the fuel quality.
This seems pretty normal, and is to be expected for the small stations up north and the ability to change/clean the filter in the bikes tank becomes the concern.

The filter is a integral part of the pump. Not replaceable separately, but you can usually clean it by back flushing.

New to the group and saw this thread. I have plans to do an ST test ride at the Bikes, Blues & BBQ rally at the end of Sept. and depending on that, will probably order an ST. Well.....I'll probably order one regardless.

When I bought my GS used, I did the external fuel filter mod to get the filter out of the tank. I then took off from Missouri for Deadhorse. I made the trip up and back without problems. The next year I did the trip again and by the time I got to Fairbanks and back to Anchorage the filter needed replacing or the bike was going to quit running. I am absolutely amazed that Nick Sanders was able to do Deadhorse to TDF three times and evidently didn't have any kind of fuel filter problems. Amazing!

If you spend enough time in Alaska I don't see how you can NOT have fuel filter problems. The gas in some parts of Alaska is less than "acceptable". Plus, you are NOT going to find 91 every where you go up there. Not that octane has anything to do with filter problems but if the ST "must" have 91, it won't have it up there.

Welcome to the Forum Harry!!!!! Keep us informed of your test ride and plans for a SuperT!!!

If you are traveling in poor fuel conditions... bad gas station fuel tanks, filters and gasoline. Could be anywhere.

Not having taken one apart (yet), I'm going to guess that there is not what we would normally think of as a fuel "filter" on the S10. It is probably more like a fuel "strainer" that is integral to the fuel pump. Something like the thing internal to the GS gas tank and separate from the actual fuel filter on the GS. I don't believe you can "back flush" a true fuel filter (I could be wrong. I have been more than once . You can back flush a "strainer" though. Unfortunately there doesn't appear to be any easy way to add a true separate fuel filter. So, logic dictates that in this case, a fuel filter isn't necessary And I guess Nick Sanders "testing" of the S10 also says one is not needed.

After researching "demo rides" at rallys, I have decided that I need to find a smaller venue to do my test ride. I'm looking at "Dealer Demo" dates now. There is one coming up in Plano Texas later this month and I think I'm going to try that. With 30K people or so going to the Bikes, Blues, BBQ rally I figure my chances of actually getting a ride are pretty slim unless I camp out at the door so I'm there real early to sign up the next day

Automotive wise, the pump/strainer assembly also has an anti siphon function which should prevent you from doing a back flush. So as the fuel rail does not loose it's prime every time the pump is shut off. In that scenario the tank is lower than the fuel rail though. We shouldn't have that anti siphon check valve here, the tank is the high point. Somebody is going to have to see if the pick-up's sock has a valve in it or not. Could blow it right off the pump and have no more filter at all. Seeing as how it doesn't appear to be a serviceable component, just ordering a sock to see seems to be out of the question.

Don, I don't know if these would work, but they seem to have different sizes.

On top of it all, looking at the parts blow-up, and it not being listed separately, the pump cassette assembly is essentially upside down. I'm not sure how the pump/sock would actually be situated in there. It would be really cool if Chevy put there pumps in like that. Two minutes to change out a pump! ::008:: Gotta drain the 30 gallons of fuel the customer just put in though. ::007::

On the V-Strom the fuel filter is replaceable but they charge a ridiculous amount for it - around $200 IIRC. There's a way of punching a hole though the clogged filter and then using an external filter between the pump and throttle bodies. Simple, cheap and easy to change filters at around $3 a pop. Been running this on mine for maybe 8k miles now, perfect.

Would like to know if there's a way to do the same thing on the S10 - not necessary now but when it has a few miles up, for sure/

The GS was the same. Fairly expensive for dealer to change the fuel filter in the tank. That's why many people did the mod to move the filter out of the tank. I don't believe the S10 would ever have a situation where the fuel "strainer" (for want of a better name) would actually plug up to the point where the bike would quit. But it also isn't trapping all the really small stuff that could end up in the injectors.

But like you and I did, an external real filter could be added if there is room to mount it somewhere on the S10. Since I don't yet have one I don't know if this is possible but it is one of the things I'm going to look at after I get the bike.

Probably never needed unless you plan on going to "bad gas" country. Where ever that is??

Does anybody really know yet what sort of filter the Tenere has? I doubt very seriously that Yamaha would let the fuel system ingest something that could plug an injector. For all we know it's got a nice ten micron filter in there. A blood cell is ten microns. Unless y'all are headed out right now to countries where they store their fuel in milk jugs and soda bottles, I think this filter thing is just...

Hey, is that horse dead? Why are you beating it when it's already dead?

I'm off to the Super Tenere Store ! !

This is such a fantastic machine. I know I'm one of the Cult de Tenere, and the coolaid is so refreshing!

If it wasn't for this damned seat... I keep going out for two hundred mile lunch runs just to see if it's gotten any better while I slept... ::001::

The fuel pump is only $320, just need someone to buy one and take it apart. ;D

And thus the internet (once again) creates a problem that is non-existant.....
