Fuel filter?

[Yamaguy55]

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.

My friend in the petro-chemical/industrial lubricants business says otherwise. According to him, higher grades do get better packages of detergents/additives/etc. He told me this years ago when I remarked I had tired of different gas cans for everything from lawn mowers to snow blowers to cars to motorcycles, and had switched to premium for everything. He said that was a good thing, as now my outdoor power equipment was going to have a cleaner and better maintained fuel system, even if the engine didn't require, nor gained any advantage from, using premium. I've since stopped doing that due to the vast amounts of lawn I now mow, but I still run a tank through the outdoor stuff from time to time.

As far as fuel grades and fuel filters: grades don't matter, contaminants and debris does.

I don't think we know for absolute sure that the additive package isn't adjusted by grade, but I tend to agree with this. Everything I read from people who are "in" the industry seems to indicate that gasoline is a commodity that is more or less universally good (or bad) - you gain little from buying higher-priced brands or grades. Probably the best thing you can do is to buy from stations that are relatively new/modern and that turn over large amounts of gasoline. What you presumably get with higher octanes is better resistance to engine knock, but almost nothing else. So I think the common sense advice seems to be the most cogent - use what the OM says.

.....and don't ever buy gas from a station while the tanker truck is filling the station tanks. Tends to stir up the crap in the tank ::005::

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...

Actually some of us are contemplating just that - so would be handy to have it figured out in advance.

 

[dcstrom]

But like you and I did, an external real filter could be added if there is room to mount it somewhere on the S10.

It doesn't need much space - found a small one for the V-Strom. Even if I had to change it every few thousand miles (I haven't had to yet at 6000), it's $3 and 3 minutes.

There we go! Somebody that has the for sure need to pull the pump assembly out of the tank and see what makes it tick. Awesome. You're taking pictures, right?

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

Bunch of puss***!

We should wait until we actually have a problem when we're 300km up the Dempster on our way to Inuvik and THEN sort it out.
What's wrong with you guys?

They use milk jugs and soda bottle up there? I was thinking south of the boarder as more Third World-ish...

You would think so but I was in Anchorage when my GS started to act up and I had to change my fuel filter that had less than 20k miles on it. I guess the point is that you just don't know when/where sh*t happens. You just know it happens.

If you're going to stay in the lower 48, you probably won't need help due to fuel "quality" issues but you'll almost always be where you can get help if you do have them. Not so much when "out" of the lower 48.

Granted, I was in Anchorage at the time and could have gotten help there but if it had happened a few days earlier or a few days later, I still would have been able to quickly remedy it because I had prepared the GS specifically for this type of problem and I carried a spare fuel filter with me.

Where as if I hadn't been prepared and wasn't near civilization, I would have been up the "brown creek" and looking at an extremely expensive and time consuming resolution to that type of simple problem.

Anyway, I should have my S10 a week from this coming Friday and then the adventure starts anew. ::021:: ::022:: ::024::

I was actually hoping that somebody might recognize the pump as being the same or very similar to a pump from another bike, then we could see what the long-term experience was with that bike... or maybe look for a used pump on ebay and dissect it...

Once you get past the '23P' in beginning of the part number, the rest of the digits are identical to that of the fuel pump used for the WR250X/R as well as some sort of Yamaha Marine engine application.
During the first year of the WR250R/X production, there seemed to be a bad batch of pumps, but that appears to have been corrected. I'm thinking the fixture that the motor is in may be the only difference between the WR and the S10, and am guessing that the motors are identical.

Ok guys, it's the same pump of an XT660 R/Z/X, not sold on the USA.

Now, has someone already done it, install an online fuel filter on an XT 1200 Z?

 

[Don in Lodi]

Just re-read most of this. Don't think anybody mentioned the fact that an inline filter won't really do much since the the filter 'sock' on the pump, in the tank, would be the one to get fouled up with crap floating in the fuel. A three year old thread, sheesh. 8)

Does anyone strain their fuel before putting in tank. We did this for years on our sailboats diesel tank and saved us alot of issues. Seems I saw a strainer that mounted in the fuel filler neck...like a sock. If you are getting fuel from a questionable source seems like cheap insurance. Anybody done this?

Saludos Carl... I am seriously thinking on doing it, but I have not find a practical way to carry a strainer....Maybe one can install one on the cap of the thank, but also, can you share with us some of the system for boats....

Done all the time when traveling in far-flung locations where you're buying fuel from a guy selling it in plastic jugs from the back of a pickup. But it's a total PITA and not something very practical for day-to-day use.

Here are some pics of the fuel pump when I had it out many years ago.

In the first pic the fuel pump is partially disassembled so you can see the fuel filter element. The other pics show a close up of the filter. As you can see the filter is crimped on and is not easily replaceable.

A bit to big to use as an external filter....

 

[Philistine]

The Ktm 690 has some sort of after market electronic box that plugs into the system somewhere, and as I understand it when you turn the bike off it performs a back flush through the fuel filter, I'm told it works very well.
I don't know if you can get these for all bikes or just the 690

Guys, I recently learned that it is totally possible to change just the fuel filter. Guys in my country, Colombia, had worked out the filter problem and they have done this mode on XT1200Z, XT660Z, R, and in MT07 and MT09. Recently I was with my pals on the second national Super Tenere national encounter and one guy had on put some 5000 kmts on an adapted fuel filter.

This is original assembly, as we know it:

Once you detach the filter, it looks like this:

Then you buy a "universal fuel filter for inyección systems". They are many, but this one, which fits many motorcycle and many small Japanese car inyección systems, is the one we use in my country for fixing this problem.

The cost of the OEM full fuel pump (with the filter) is about 400 USD, but the "universal filter" is about 5 USD.

The pump uses a filter system called a PRE FILTER FUEL SOCK or just a FULL SOCK. If you search you can easily find them online, for example http://www.jayracing.com/fuel-filters-c-2_14/bosch-fuel-pump-prefilter-fuel-sock-for-044-p-62.html.

I am sorry I can't give you a better link. I just can buy these filters over the counter. The one we use on Colombia for these bikes is from a car called Suzuki Sprint or Chevrolet Sprint.

I need diameter of the plastic cupling part is 11 mm or 7/16 ".



BTW, pressurized injection systems on bikes and cars without an inline fuel filter have a pre-filter and it's not possible neither advisable to install a inline filter. Just stick to the fact that the pre-filter or fuel sock can be replaceable.

I hope this news help many of you.
