I see Oetiker clamps.... I see the pressure regulator.....where is the nut you are talking about? Am I blind?
Matryx boost fuel pump

Guessing the clamp ring that holds the pump to the tank.
Yep, again I don't see how that would contribute to the pump noise or burning up.
Shouldn’t make it burn up but could allow the pump to vibrate and make noise?

Not true, u have a ****ty dealer.
Mine was replaced with no questions asked.
So is there an aftermarket available? Does anyone know if the aftermarket axys pump would work?

Mine failed today at 16 hours about 280 miles, it starts whining and then cuts out on a hard pull and low fuel pressure warning comes up. Polaris must know there is a problem.
The sooner Polaris puts out a service bulletin, the fewer days of riding and and trips will be lost by 2022 owners.
Lost mine as well about the same mileage, sounds like it will take awhile to get one back ordered
So my pump whined all day yesterday, this morning we pulled the body work off and the clamp ring that holds module in tank was tight. We pulled the module out and couldn’t see anything visibly wrong, so we put it back together. The pump was completely silent when we started riding this morning. By the afternoon it made a little noise but not as bad as before. Never got the low pressure warning today. Sounds like the pumps are on back order til 4/01/22
Thats why i haven't accepted mime yet. Still not sure when I'll accept it.

Pretty sure Vohk is claiming one of these plastic ears on the regulator can come unhooked causing fuel to leak past the o ring, giving a low fuel pressure code. From what I have seen there is more to the issue then just the regulators as many of them have been fine when taken apart. I think it is just a bad batch of pumps, a service bulletin on this would be great.

Have any of you guys had your sled become hard to start after your fuel pump started making noise? Mine started making alot of noise today and then the last couple of times on the way back to the truck it would take several pulls to get it to start. Also what temnpature have you guys been at when pump started making noise? I was in 40-50 degree temps today when mine started making noise.
All you guys with the pump noise, is it just when the fuel gets low ? Thats what we noticed on 2 of them, Top them up with gas and the pump stops making noise. Also with low fuel 30-35% on a climb, they get a low fuel pressure code, until you add some gas.

My buddy's was howling again today. More or less full
Only taken it twice and noisy both days. Wasn't a fuel level thing. It wasn't howling right when we left the truck because I was the one running it. Bet it was at 90% when I gave it to him.

Did you happen to pull the pump out of the bracket and search for numbers?
I've had luck in the past finding just pumps this way. One truck I was able to buy a $38 pump instead of the $350 complete bucket. Couldn't find any reference anywhere until I found a number engraved on the old one.
I can't imagine they reinvented the wheel. Looks like any old wahlbro 60psi pump.
Yes there are other people who did that, but no such luck finding an exact replacement from what I saw.
It's not just the boosts - my NA crapped out yesterday - high pitch whine all the time and low fuel pressure warning any time I got into the throttle hard. Shut it off, wait a couple minutes, restart and no warning as long as I kept the RPM's down. Dealer said no idea on how long to get a new one - at least it's on order.
