How To: Clean / Replace Fuel Filter on a Yamaha YZ and WR 

Ya, this video doesn't do justice to just how big of a pain it is to get those 3 tabs loose. Couldn't have done it without this video. Much appreciated!

Thanks for this video, you saved me buying a new assembly! I bought a 2015 that was ridden for 3 hours and then sat since purchased. The regulator, pump and filter were caked in old gas gunk. Thanks man you’re a legend.

Awesome video man! 👍 I was looking for a replacement fuel filter for my 250 bike too. I didn't find any replace filters on ebay, do you have a link to buy one? I was also wondering how you clean your filter?

Nicely done man, very well made video. Gonna help lots of people!

Thank you for the help youre a hero❤

Thanks man your video was hugely helpful. Just cleaned out my filter. I found that contact cleaner and compressed air cleaned it out beautifully. Looked almost brand new

This fixed my bike! Thank you for the information. 😁 My 2020 YZ450F has almost 500 hrs and started to stall (run out of fuel) when it only had 1/4 tank of fuel and I was going over whoops at high speed. After the cleaning it runs strong until the tank is completely empty. 😎

You have inspired me to filter the fuel while pouring it into the bike. The fuel pumps are pricey at over 300 bucks.

Thank you !! I have about 240 hrs on my bike and I think this is my issues. 👍

thank God, this is exactly like my fuel pump except that I have the fuel filter exposed out so all I need is to pull the pump outta the tank and change the filter, I can even see the filter though the tank hole . but that also helped my a lot thanks. (I think you can buy those filters got mine for about $5 but slightly different for yamaha FZ150i)

Thanks for making this video Josh! I will be doing this tomorrow. My bike cuts out like its running out of fuel when i get to a 1/3rd tank of gas, hopefully its a clogged filter...keeping my fingers crossed.

The difference between this fuel filter and the WR250R-X is there is not a shroud over the WR250R fuel filter. once you've removed the fuel pump from the WR250R use contact cleaner to clean the filter with no further disassembly or assembly required.

Thanks, this helped me quite a lot. I used it for a 2013 Yamaha XT-250 and it will probably work for any year fuel injected XT-250 since they don't seem to change anything except the colours year by year. I found that I could leave that connector that you have on the fuel line coming off of the pump, back on the hose still attached to the bike, made for an easier job of things. You have to squeeze the two tabs on the connector while pulling out the hose, would be a lot easier with a 2nd person as would most of this job. I elected to buy a new filter, got 3 for $18 from Quantum, they don't look as nice as the original but I hope they will be good...I didn't want to go through all of the trouble of taking apart the pump housing more than once.

Is the fuel pump supposed to dribble gas out of the connector ? When removing the gas line?

Thank you, it would have been hard to do this job without your video!

👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼

Thanks for the video. Easy rebuild with this info.

Pulled apart my Yammi YBR125 pump today. Sympton was non-starter, but turning over okay, yet not firing. Squirted some juice down the spark plug hole and fired okay, so started looking at fuel supply. Could hear the pump prime okay when turning on ignition, so presumed that was okay and instead went to the injector. Took off the injector and connected to can of carb cleaner with a tight rubber tube and squirted through okay, so wondered if there was a pump issue afterall. So, stripped it back (as per this video - pump unit is fairly similar), submerged the pump + filter in a bucket of water and connected the pump to power. Horrible cloudy crud tried to ooze out with barely any force. Removed filter strainer and tried again and was happy to see that the crud came out better and then in a few seconds was shooting water through at a good pressure. Dried the pump and air-lined it to dry inside. Not gonna try to re-use filter and will get a new one on Ebay (just looks too far gone and don't want to have to strip down again to replace at a later date). Glad to keep the original pump, so hoping it will be okay when it all goes back together :) Thanks for the video Josh - really helps to give me a bit more confidence when I have seen that someone else has overcome a problem like this. Cheers. P.s. Likely all my own fault as I do barely any miles over just a few months of Summer riding and topped up last Summer's petrol that was still in the tank :( When I emptied the tank to get to the pump, the fuel was really yellow - yuck! Gonna look to just throw away old fuel before start ing afresh next Summer :)

Thank you, worked perfectly.

What was the symptom that led to cleaning up the filter

How do you clean the filter

Hey! I was able to follow your video and clean my filter. didn't solve my problem though. my bike cuts out doing a long stoppie unless I have a completely full tank. I'm assuming its fuel pump or sending unit related. I tested it by recreating the stall during stoppies and then filling the tank and had a friend lift the rear end to balance point while I held the front brake. ran fine no stalling with a full tank but when starts to stall at 3/4. I'm going to order a new fuel pump assembly.

I didin't find any replace filter on ebay.

Thanks man!

is the fuel pump for a 2015 yz250f and beyond the same as a 2004 yz250f fuel pump not sure if you respond i well be a happy man THX.

You still ride Yamaha

friend a question, do these pumps have some kind of check valve to keep the fuel in the system? I ask him why my yz450f 2015 takes time to turn on and the mechanic says that the pressure of the pump drops and the system discharges, the clock shows 46 psi while the motorcycle is on when it is turned off it drops to 0 psi immediately

yea, ive got a 15 yz250f with problems. Third time customer rode it locked up. So I checked recalls shocked to see them all actually. Ripped motor out took all the way apart. Generator wheel nut came loose, generator wheel justlying there. spun on the shaft broke the key. Bought new wheel new key tested, everything ohmed out, still wont start. Checked all the sensors they all ohm out. Now no freakin spark. I cant beleive the whole harness has one ground on this bike. Oh I was giving you poop becasue use carb/efi cleaner not brakekleen on your fuel stuff. Please. lol

Do you have a video pulling the throttle body out?

By cleaning the fuel pump would the bike run and idle better
