24 fuel pump or something else

[josh@andeon]

Had the 24 boost out and the fuel pump whines worse than a fat kid when someone stole his lunch. Took to the dealer he said that’s what they do. But once I am down to half a tank and i wheelie it bogs and then Gos into a limp mode but no codes. Will not rev past 4500 rpm I shut it off and all power is back until I wheelie again. Really sucks when you’re in trees. Any help is appreciated

don't wheelie.

New filter and regulator. It's losing fuel pressure and when you go wide open it's dropping far enough to throw a code.

23 Boost doing the same thing. Dealer could not duplicate it running it on a stand. Imagine that. So now I wait for snow to deal with it again. Wishing someone could figure out a for sure fix.

I have a 22' N/A with fuel pump recall done and it's doing the same thing. I have researched for an after market pump and NOBODY has a direct replacement that I can find. A new Polaris pump assembly
(can't buy just the pump) is over 1000 dollars in Canada. Sucks to think every 1000 to 1200 miles I will have to buy a new pump just to ride my sled (no warranty left) was hoping The latest fuel system recall would be a new pump and have called customer service and they have NO fix as of yet. Love the sled but Polaris's QC SUCKS BIG TIME!!!!!!!!!

They should warranty the pumps for at least 3 years given all the issues with them.

There are a few things to check.
You will need to pull the pump.
On the pump assembly, check that the line coming from the back filter is inserted into the black box. Make sure the FPR is completely seated, check out the pic. We have seen a few like this.
You may need to replace the rear pickup sock as well, it may be a 10 micron instead of a 30.
On my personal sled, I installed a brass fitting in the assemblies return line. It stopped the whine. I believe the returning fuel needs more residency time which affects fuel temps and adds a little back pressure to the pump.
As you can see in the pic, by the color of the sock, it’s now drawing fuel through it. It’s a 30 micron sock.
Also check your fuel temp, fuel pressure sensor. Make sure the connector is seated and locked.
Just for your info, the Boost pump is a 180lph pump vs the 150lph pump on a NA sled.

How do you know if it’s a 10 or 30 micron sock? I purchased kit PN 2209832 filter kit and installed but didn’t get an opportunity to test.
My FPR looked good and was seated like it should be.

PN 2209832
That’s a 30 micron kit.

PN 2209832
That’s a 30 micron kit.

Is 30 microns the OEM rating for 24s? And was it 10 microns in prior years?

 

[TRS]

Originally 10 micron in 22. Updated filters are 30

Originally 10 micron in 22. Updated filters are 30

Is the larger filter pore sized supposedly to reduce the vacuum in the pump and increase/maintain the flow at high boost/fuel consumption levels?

It’s been that way since ‘22. Over 2000 miles on it. 100% non eth. But it may blow one day. Still waiting on the recall notice and decals.

i wonder if polaris will ever figure out this whole static e problem.

Could look into Quantum AF. They use Walbro pumps for their pump replacements and kits. I've used them for my KTM dirtbikes for several years with great success. Haven't used in a sled but when I researched them.a few years ago, the pumps they use are solid. https://www.highflowfuel.com/search...laris&Model=Patriot Boost RMK KHAOS Slash 163

Make sure you check pump flow and pressure before you purchase one of these pumps for a Polaris.
Boost 180lph
NA sleds 150lph
