Anyone want to share what the fuel filter part number is?

Back ordered from Jegs. But that’s it.

Summit or direct from Hyperfuel Systems? (https://www.hyperfuelsystems.com/products/fuel-filter-10-micron-orb-08-46080).
BTW- reason for 10 micron is any particle smaller than about 25 microns will not cause an issue in fuel injector. It will go right through and not plug it up. Anything about 35 microns or bigger will get stuck in inlet screen of the injector. NFG! Must have CLEAN fuel going to injectors, especially on big tunes with stock injectors because there is less margin for error.

1950 miles on mine this year. Filter installed from new. Off season will be cleaning. Was planning on using carb and choke cleaner. Sprayed opposite way fuel flows. After pulling screen. Unless another idea is better for cleaning?

For those who read my "998 rebuild" thread, you may recall part of my diagnosis and rebuild was to have my 3 fuel injectors cleaned and flowed to ensure they are at 100%. As it turned out, when I did that, 2 of 3 were 3.5% down compared to the other. While 3.5% may not seem like allot, if you're running a stock fuel system that is maxed out and close to the edge at times (like when it's really cold out or gas tank is below 1/2), it could be important. My injectors were cleaned and flowed and now all 3 are at 100%, or should I say all 3 now flow the same. The company that did the cleaning told me that I should have an inline fuel filter to protect the injectors (just like many cars/trucks). They said any debris larger than about 25 micron could become lodged in injector inlet filter or even into the pintle and seat area. Therefore, I set about trying to find an inline filter. We do have a strainer in the tank (connected to pump inlet) but it is only able to protect the pump as it will only protect down to about 40-50 microns. That size debris will easily plug up injectors. I'm actually surprised there aren't more problems with this. I wonder how many 998 sleds out there right now have restrictions in fuel injectors?
Result - I now have a 10 micron inline filter right before the fuel rail. It will flow 240 gals/hour and has a cleanable stainless steel mesh element. It is located under the handlebar mount and right behind the existing fuel rail. It is 1.25" diameter x 4" long. I used the factory 90 deg. quick connect on the hose that comes from the outlet side of the filter and another 90 degree standard automotive quick connect on the inlet side. Note: the factory fuel rail quick connect is not standard 5/16" automotive size. It is a special Yamaha size that is close to 5/16". The inlet fitting to the filter is standard. I shortened the factory fuel line and installed a 90 degree fitting to get into the filter, then the outlet side has a standard 6AN 180 degree fitting and a 5/16" fuel injection hose to the factory fuel rail that connects with the factory 90 degree fitting. In the pics it is hard to see but if you look close you can see the 90 degree into the filter and parts of the return to the factory rail. Now my injectors will never get debris in them again.
If anyone is interested, I can give you the part numbers for the parts. I got them from Summit Racing.

Looks great. As an FYI, in the old days Yamaha put the fuel filter inside the bottom of the tank as part of the fuel pick up. I changed one in 1980 SRX last fall. I was actually thinking the same filter could be used inside the tank of a new one. I am surprised there is not one on the line somewhere. My 1100 has one but for some reason Yamaha/Cat decided the 998 did not need one.

IMO, it does need one. As part of 3 rebuilds I did last summer, I sent the injectors out to a company that ultrasonically cleans and flows fuel injectors. Of the 9 injectors, 4 were down on flow due to debris in them. Not good. After cleaning, all were 100%. BTW- from marking the injectors before sending them for cleaning, I know those which cylinders they came out of and the cylinders that had the worst deto damage had the dirtiest injectors. Think that's a coincidence?

They need a filter, but cutting corners seems to be a common practice now days. Its almost as if they are building them to fail after so many miles.. Then you can buy another for 5K more then you paid last time?

There is a filter in the tank on the end of the pump, but the micron rating isn't fine enough to keep debris that clogs an injector out. Great job @Turboflash

 

[Turboflash]

Yup. I call that a strainer rather than a filter. Most automotive fuel systems have same. Problem is most strainers only capture particles about 40 microns and larger. That size will definitely clog an injector.
Through the cleaning/flowing process I was informed by the company I used that these injectors do have a small filter where the fuel comes in. And, they do put new ones in during their service. However, those filters are so small, it doesn't take very long before the fuel flow is restricted. They totally agreed the best thing to do is to prevent the contamination from getting into injector in the first place. Hence, my motivation for installing the in-line 10 micron filter that is made for post-fuel pump EFI applications. BTW- if anyone is going to install a filter make very sure it can flow enough fuel (GPM). And, keep in mind there is up to 65-70 psi of fuel pressure on big tunes. The filter in this thread above can flow way more than any 998 needs.

I have a 17 LTX SE. I thought I had read that the fuel line is different on the older ones that the newer ones like what @jonlafon1 has. Is that true? I haven't looked at mine yet to see what type of fuel hose is on it. I am interested in doing this before next season. I see that the filter has female threads so it appears it would need some sort of barbed fittings to fit the fuel line.

Just a heads up for you guys adding a filter. Dont trust clamps. Any clamps. I believe mine failed from corrosion jacking. Dont know but think of all the newer vehicles. No clamps. No issues. Just saying.

Recalled Fuel Line Leak

Not good! Knew I smelled gas last night daughter said she didn’t.

On the 2022 I simply cut off the fittings from the "plastic" fuel line and used the 5/16 fuel line. Its a cake install, you will have no issue. I have to go back and look.. But I ordered 2 fittings for ends of filter that screw on and have a 5/16 barb on them. Also rubber O rings that seal things up.. I lightly oiled the rings and snugged up the ends to the filter. I will post up fittings when I find my order for them. It was not from Jegs

No way to install a inline fuel filter without clamps? I understand the molded plastic fuel line and why they did it. But how else can you install a filter?
