 Unanswered FP-HUS Replacement fuel pump for WR250R

PostSubject: Unanswered FP-HUS Replacement fuel pump for WR250R   Wed Jan 02, 2013 6:06 pm

On the Adv site, WR250R thread, Someone asked this question in the many "fuel pump failure" posts but I'm not sure anyone ever answered it so I will ask it again now (and yes I did the search to see if it was ever answered and I do not believe it was).
The FP-HUS fuel pump from California Cycle Works was cited as being a suitable replacement for the stock WR250R fuel pump. The question was asked if this pump can be mounted/attached to the stock fuel pump "basket mount" or does it hang from the fuel line and "free float" in the tank without being secured. Has anyone here performed this replacement? Would it be a viable "field repair" or would fabrication tools be needed? Thanks in advance for you patience and hopefully answers.

Hi Aleeoop,

NO. The current model that we sell has a barbed outlet which doesn't fit into the plastic cage above the pump. That's what we were told by our Australian distributor. We're Ducati guys and while I previously got dirty, I'll be quick to say I and we don't know much about the off-road market.

The FIRST production run did not have barbs on the outlet. All the Husky people yelled at us so for the 2nd run, we had the barbs added to the pump. These are long sold out and not available. We did need the barb as when we spec'd the pumps, I asked that they endure the highest pressure possible and be the best product the factory can make. IMHO, on the Euro bikes, there's a design flaw in the fuel system which puts an undue strain on the OEM pumps, which are probably ok but not designed to be mis-used. By coincidence, our pumps are helping the Husky folks because it seems to cure the symptom their fuel system problem presents: a failed OE pump.

If we can find a wider application list than just the WR250, we will consider requesting another production run of our pump with the original smooth outlet and designate it a new part number. If you can help us learn the full application list of models that can use this pump, please help out and send us an email to orders@ca-cycleworks.com

Thanks for your consideration and apologies about the confusion,
Chris

Hi Micke,

Thanks for writing back! It sounds like enough parts to make inquiries about. There has to be more Yamahas that use this pump though...??

Thanks,
Chris

Hi, Chris! Thank you for posting back so soon.

I don't know if there are any other motorcycle or powersports models that use the same pump assembly. Maybe some other people will comment. Maybe not, apparently.

Thanks just the same.

haha that was probably me poser2 Glad I could provide some useful info.

A couple of months ago my fuel pump died and I heard a rumor that the FP-HUS fuel pump was a replacement. So I ordered the it from Brad the Bike boy the Australian Distributor (very helpful guy thumb ) but it turned out they changed the design a few days/weeks earlier and I ended up with the new design which didn't fit. baldy
But I managed to swap the pump with the first production model. I installed the pump into the cage, it fitted perfectly, turned the bike on, it had a different priming sound but the bike ran great and has been running great since. I'm glad I went through the trouble of getting the fuel pump because now i have a higher quality pump at about half the price of the yamaha one!!!

Is the ID of the outlet the same between the two pumps ? Even if it isn't exactly the same, it doesn't look too difficult to modify the barbed outlet to a smooth one.

I think the internal diameters are pretty similar. When i got the first fuel pump I thought about modifying the outlet, the hole the outlet goes into is large enough that the barbs don't affect it but you would need to cut the outlet to length and there is a metal rod that runs down the center with some plastic bits around it so i think if you cut it you would damage it and i don't know what it's there for.

The inside of the outlet on the cycleworks pump is similar to the yamaha one:

Chris@ Ca Cycleworks or anyone else, what is the purpose of the metal rod ? Does it mate with the fuel pump body for alignment ? Can it be trimmed ? Personally, I can't see how shortening it would affect it but who knows.........

Good to know trimming it to length is the only modification required since Nick says it fits with the barbs intact. .

Is it possible the metal rod is spring loaded to prevent reverse flow and keep the pump primed?

Hello everyone!

We've created a fuel pump just for you! It is $129 just like the FP-HUS we sell. The new part number is FP-WR: Find it here: http://ca-cycleworks.com/fp-wr

Well hell yeah! I’m still using the stock pump on my 08. But if this is a direct swap and performs better or equal to the OEM pump Im going to have to get it.

Can so somebody tell me what is better about this pump? I have no issue buying one if it's truly better, but all I can see is it's a different color. I'm about to replace my tank & would consider upgrading the pump while it's out.

Thanks,
Buddy

The pump is designed and made by a company that specialises in fuel pumps and I believe is of higher quality and will last longer than the yamaha pumps. I think its a good idea to replace the pump while the tanks out but be very careful with the fuel pump cage as the plastic doesn't like to be bent and can be cracked easily.

PostSubject: Pump Info for Buddy   Sat Dec 28, 2013 6:52 pm

Buddy/4play:

The pump is supposed to be top grade, that being said, I have a 2012 with > 21,000 miles on the stock pump with no pump issues (there's a jinx, I'll be walking out of the desert). This pump will not make your bike go faster or jump higher. You however, are in that 2008 model year that had a lot of faulty pumps. This vendor is supplying just the pump, not the whole fuel pump assembly (filter socks, fuel level sensor, multi connector, wiring, seal, etc.). It will allow you to replace the component that has problems for less than half the cost. Since I can't see how much mileage is on your bike, I don't know if I would worry about your pump or not, but 2008 was a bad year for WR250R/X fuel pumps. The faulty pumps caused a later modification and it is now more reliable. If you go to your OEM parts for the 2008 year, you will see that the pump part number has been replaced.

Also keep in mind, this pump will be slower to install. You are not swapping the pump assembly, you are removing it and meticulously switching out the pump itself without breaking the assembly.

Hope this helps. . .

The bike is an '08 with just under 2000 miles, I pick it up Monday.
The previous owner had TWO pumps replaced under warranty in the 1st 1500 miles. The second was supposed to be an updated pump & is working fine. I'll be installing a larger tank right away & would have the opportunity to upgrade the pump. I ride some very remote trails & I need it to be a reliable as possible.

Thanks

I suggest you pull the tank and check the part number on the pump assembly. If it is the current number I would leave it.  If it is the old one for sure switch it out.

I dont think the part numbers matter much. I was supposed to have a better fuel pump in my 2010 WRR but it still seized up and had to replace it.

Have to disagree. Seemed that way for a while, so I see your point. They "supposedly" addressed the issue, but the problems persisted until the 2014 revision. Mine is a 2011, and it too failed. The 2014 part # was used for mine, and I have NOT heard of any failures associated with Yamaha's latest iteration.
