Matryx boost fuel pump

[snosfun]

Has anyone figured out what is going on with the boost fuel pump failures? Why is it happening? Is there something we can do to stop it from happening or fix it after it happens?
I'm afraid it will happen to mine when I'm on my big trip and fuel pumps will be on back order by then.

If yours is starting to make noise it wouldn't be a bad idea to have a spare in the truck/trailer.

For $1500 I doubt many here will just bring one along especially since most of the Maytrx sleds will have warranty.

Mine started making noise yesterday. Dealer is telling me it has to stop working for polaris to cover it

Sounds like the aftermarket could make a killing if they can do one for $500.

That's nuts for a fuel pump. Racecar prices aren't even that bad.

So if the fuel regulator comes unclipped, why does the pump make noise? Is it over speeding because it doesn't have normal working pressure?

Skidoo pumps did the same thing few years back, regulator popped off the pump
The fix was longer screws with a washer to overlap the regulator

I heard a slight hum near the front of the sled. Thought it was the new primary with how that works with the belt. Better investigate this more.

Couldn’t hurt to take a look at the pump/regulator
Zip tie it for the season
If you yank the pump take a shot of it for us! Please!

My buddy's boost has more than a slight hum.

FUEL PUMP UPDATE

Took the boost into Polaris today after a bunch of checking other sleds. 4 out of 5 2022 sleds had the fuel pump fastening ring only finger tight. Torqued the ring to factory spec 28ft/lbs. seems to have eliminated the loud fuel pump noise. It is completely silent.

I won’t be able to take it out and test it for about a week due to our snow conditions! But happy to be making headway!

Any one have a video or picture of how to check fuel pump. My sled seems to have been built on a good day as I have had zero issues and I check for some of these problems others have had and have yet to find anything. Fingers crossed.

My first ride yesterday. Fuel pump started making noise at the 15 mile mark. Sled never missed a beat all day though, but still pulling apart to check it out.

quantum fuel pumps work well. $600 yamaha outboard fuel pumps are $80 from them.

Pulled it out of the tank and I don't see anything wrong with it. Nut was tight and pressure regulator was fine.

We rode yesterday couple hours. Noticed the pump making noise when I started it to pull in trailer. Howled all day today I got the low fuel pressure fault one time on a pull. Didn’t happen again

I see how this could pop apart

Does the fuel level sender snap in the tank somehow?

No, just lays on the bottom of the tank. The stiffness of the hoses holds it in place I'm guessing.
