My fuel pump failed on my 510 around a month ago. Did lots of searching to find a reasonable priced OEM unit. I know there's after market stuff out there but I like to keep the working parts genuine.(Excluding Bling) . I can't really say where from but it was from the good old U.S. of A. I was going bonkers waiting for this thing to clear Canadian Customs. Anyway it's here...it's in my bike and I'm a Happy Camper once again. There's nothing like to power of a 510.:ride: Here's the old pump I opened like a tin can. The impeller was covered with a fine grit or silt. I did clean it off and hammered it back together again. The bike would idle with the old pump in, but not rev. I really don't think they're made to come apart. Here's the new one with some obvious changes. It even sounds new when priming. If you're in search of a New OEM pump throw me a PM.
So that replacement pump is OEM? Is it the same part number as the original? Keep us posted on how it holds up!
I have never had the pump out of my 610, so I don't know much about what is going on in there. But I was curious if you think the pump failed because of impeller/housing wear? Is the fuel filtered before or after the pump? I should know this, but.. better late than..... Do you think the silt caused the failure?
The 2011 pump is completely different again. It actually is the same pump that KTM is using in the Bergs.
The small motor would no turn over. Even with external power. But once apart and cleaned it was fine. I don't believe impeller/housing wear was an issue. But once I hammered it back together it was. When I put it back in the bike it would idle but not create enough psi while revving. The impeller/housing wasn't sealed enough. These pump are not made to come apart. I knew mine was fubar and I pretty well have taken everything I own apart since childhood...bad habit... The fuel filter is downstream of the pump, meaning the pump is not filtered. There is a fine nylon like screen on the pump intake but not fine enough to stop the silt from entering the pump. Yes I do...on mine, not sure of other pump failures. I would have just tossed the pump assembly in the trash...but what's the fun in that. Scott what have they changed on the pumps? Can you post a side by each pic for us?
Interesting, I suspect the pump can't create enough suction for a real filter on the inlet or that is where the filter would be. A diaphram type pump might have been a better choice?
Same set up on all fuel injected cars. They use a sock (fine nylon screan) to pre filter pump and use the real filter post pump.
I havent seen the 2011 pump but my tech was at a 2011 training school last week and he told me that the pump was all new for 11 and that it looked just like the Husaberg pumps that he has seen already.
That is good info for people to know... Its like I said to a couple guys: "apparently most are finding crap in their fuel pumps-" (and here's the technical part) "Crap is ruining pumps, so don't put crap in your tank"... Wish it were that easy to prevent.
wow , you mean I can buy just the fuel pump and not the entire $500 assembly?????? I am curious as well.....
I have a 2010 Te450 with 100 miles that wont stay running for 20 minutes, I would GLADLY buy ANY fuel pump that was a 10.6g/h (40 l/h), non-return fuel circuit, 43 psi. Could you please post or PM me with ANY info you have on ANY fuel pump that will work on a 2010 TE450, I dont care if its not OEM Thanks
If the old assembly is not going to be used - please cut open the filter. I'd like to know if it's plugged with this fine silt as well. Since the pressure regulator is after the filter - and the filter is after the pump - a plugged filter would force the pump to run at a much higher load (output pressure). Dead-heading a vane pump this does not have an internal bypass is not a good thing at all. That inlet sock looks pretty black too - you might want to wash out the tank. I remember mine as being white. (2009) IMO - MAT
Good point I'll take the filter apart tomorrow morning and post up. But with not having a pre-filter before the pump I suspect the internal filter will not be plugged.
