fuel pump
05/05/13 7:46 PM

Well as the heading may suggest I have some issues. After checking out my whole bike checking everything top to bottom. I finally narrow my trouble down to you guessed it fuel pump. Well really its the pump that went bad but the tank was the real problem. now I am looking at the tow yes I do think there are two fuel filters or strainers more like. Now we can open this topic up in maintenance. but i just wanted to ask if anyone knows where to get the part number for that lil filter strainer thing on the pump inlet. pictures will follow in the maint. sec...xxxses

You are correct.

Romans, that bottom pic looks just nasty! Although not specified in the service manual, I get the feeling that it might not be a bad idea to change the filters every few years...

Kawi sells no filter parts is my guess? It's a new pump unless these are auto type replacement parts from the Japanese imports. We just dug in to see things, Romes, or are we replacing with a part number say?

Which is rather silly. Fuel bag strainer should be a 2 dollar part and part of our routine maintenance. Bag shown above has less than 10,000 miles

We just dug in to see things,

Was playing with stock housing to retrofit Walbro 255. If you see top of pump it has what looks like frost plugs. They kept popping out due to clogged filter and me forcing to much volume through that tiny orifice shown above.

Easy to see why pump fails. The pore thing has to pump fuel through bag strainer than fuel reg, then paper filter out tiny orifice.

I am NOT 100% certain so I did not want to start the thread off with any wrong info....but if mememory serves, this topic has been mentioned in the past and the answer is as Hub said, replace whole pump. Replacement filters not available. Needlessly poor design, IMHO. This is as basic as an air filter or oil filter.

I'm 50 + 15 = 65 in the hole is the one filter-3 I can see and the clip-5. What about main designated name of filter-2 @ 270?

For the same 'throwaway' price, I am saving money because it has to filter more than what #3 is filtering at. So that is one filtering stage. Are you going to see strainer and filter as two components to change, if we are about to salvage pump blades to keep 44psi in the constant?

2nd filter Can Never be changed molded in. Filter bag is first line of defense. 2nd filter before injector out side tank = simple ?

One extra to look out for,We removed the fuel tank this evening on the 07 14 found the fuel pump sitting in water.The drain hole in the plastic was plugged with debris,cleaned it out and drilled the hole larger.Thinking we caught a problem before it became an expensive problem.

D-IS Year Warning or WEaring Badge IS... =
05/07/13 8:56 AM

... Do not step on my car pit, d-is pit speak, wear out I sneak up on year trophy, you go racing withe turtle talk.

The first line of defense [filter] is a band-aid fix. If the porosity is that flow-able, so says the 2nd filter is looking 1/2 as bad with the microns that did move past the first line/0d filter. Then say, a 1/4 of those microns attacked the blade and wiper cage finish.

If you could [collect] and line up the tiny gouges, gave depth and width to it, we have an air gap, a liquid gap, a pressure loss gap. I am now 1/8 of a micron, was swept under the blade and my ass got burnt. I am now down to a 1/16 of a micron, and am heading for a spray hole opening at the injector: along with my ass burn. I cannot create or destroy ass burn, so I will collect like bird finding twig. I'll nest all my micron ass burn is sit here is to give you a spray like if I held my thumb over a hose and let the water shoot off to the side, I cloggedat assideways.

And you know that cage wipe is also material gone [unfiltered] meaning, hose say can you see is me thumbulleanHA?

I'm in the hole close to 80 bucks adding new rubber on the tank seal too. I can only change one filter and both look about even as per micron movement. I'm still looking at wiper blade and cage wear, where I have to reach around the postear we are back up front to the zipper, pissing away 100 bucks worth of shipping is the total? I'm looking @ 42 psi with a $100 filter is a 1/3rd of the filter is repaired. I'm going to clog more of the 2nd filter that's 1/2 clogged already. Ah, 40 psi and; 'Hi, new here. When I WOT her, she falls on her face. It's all stock. Leak in all 4 read 2% leak. It's not compression. I changed the plugs to OEM to keep that variable out. I have spark/compression/WOT do you think is left?': Is one variable = Fuel pump pressure for $300, Alex.

I have my $100 half/ass'd filter on. I have the other filter like a front sprocket I'll leave alone. Wear out the new rear sprocket and new chain over the old sprocket and eat that up in 1/2 the time is the front sprocket is well over 1/2 done. I need to keep the used front wheel on the bike with the new rear tire and hammer into a corner with a used front, look ma, no KFC's on the front!

Ooopseas! My bike did some lawn care on someone's property. I thought I had more rubber on the front?? So I'm back at the dealer's counter, they won't lose a sale matching net. You win with no shipping. Your second round of fuel slobbering out the 10 or 12 holes, she is going to have more yuck behind her orifice-is might ass well reach around, have the injectors cleaned while you're at it.

You have this 1st defense drag heading up to a second, wink-wink, sea change is wear out I'm going ~ rev-rev??

Lol, hub U funny sometimes. Hub I only know you through the net But I can make this next statement with ZERO Doubt.

If those two filters were maintainable You Would Be The First To Be Changing Them before pump wears out. Tell me I'm wrong ???? got cha lol

Almost like were saying every 40,000 miles get new pump or ? Filters must B dirty, No ?

I just saw here one of our members hit a 100,000. No way he has 42 psi. Well, I should say, I would have to see it to believe it. Is he lean, maybe not, but his Air Fuel Ratio def moved a couple of points.

If those filters were replaceable, I'd have them lined up like I do the OE oil filters. You are correctoe moon dough, Romes. And yes, If 100,000 plus boy is riding in that filth of a city, that bike is still running, meaning, I think the filter has a long life before the bike gives out? If you think about it, an electric fuel pump has been around for a long time. They need to be cooled or they fail quick. Other than that, you have some that needed replacing, but most are as bulletproof as the bike.

Should I pre-filter the gas at the pump? Hard to do unless you bring gallons home and filter it that way. But am I that anal knowing 100k boy is running fine? I'll take, No Way Hose Say for an 8 gallon gas tank, Alex.
