Fuel Pump/filter Problems?

Having a problem with the filter in the fuel pump clogged up will not let the quad run. Has anybody removed that filter and installed an in-line filter?
Or anybody have this problem, the quad will be running then just start running like it is out of gas. Cleaned the filter thought it fixed it then it started doing it again.

No problems here. I'm out of town but when I get back I'll take a look at my manual.

I have experienced this problem with both an LTR and a Renegade. Both were race bikes and both were used in the desert.......lots of dust and sand. I have heard of similar issues with a couple of the fuel injected bikes also.

In every case it has ended out being the filter in the fuel pump assembly. With the Suzi we replaced the filter with a new one and it never happened again; with the Renegade we chucked the filter altogether and replaced it with an in-line jobbie.

Uppon checking the filters they both looked clean and that was the problem; we thought they were clean and just put them back in only to find out the problem wasn't fixed. We had to cut the filters open and look at the insides to confirm the issue.

That is exactly what is happening, cleaned it thought it was clean problem wasn't fixed!!
Did it work good with the in-line filter? That is what I'm ging to do, I have a new pump ordered will use the one with in-line filter as a spare.

It sounds like the LTR problem. With the suzi its before the pump but on the 700XX I think it's inside the whole unit. There is a tea-bag looking filter; that is what's getting blocked. To test that this is the problem take the fuel pump assembly apart and remove the filter altogether then take it for a spin. If its the filter you will know.......if you still have the problem it may be a blocked injector. I think it will be the filter though.

Like you said after cleaning it looks OK but we cut the filter open and found a small clump of dirt right over where the hole was, my guess is that the pump is sucking the dirt over the hole and blocking it.

The suzuki was OK with a new filter although many people ditched it and replaced it with an in-line filter from a car; just make sure it flows enough. The Renegade was only fixed after we did the in-line, if we just replaced the pump filter it would happen again.

Suzi only sold the whole pump assembly so you could'nt just order the filter........they ran out of pumps and then offered the filter as a spare part.

I hope that helps

Sure, they don't want you to open the fuel pump and fix the problem yourself. They'd rather sell you a new fuel pump at about $105.00 rather than sell you a filter at about $10.00. You can order just the filter from babbitsonline for $9.95... or you can order the filter from your dealer. The Honda part code is: 9181157

You also should check to see if your fuel itself is contaminated with dirt or other crap from the trail. If the fuel is contaminated it'll just clog up the new filter soon enough.
