Fuel Pump Whine is Back (2022 w fixes)

[JeffBrines]

I know this has been discussed to a nauseating degree but I wanted to see if anyone had a real fix for the fuel pump whine. A little background...

1) My pump was swapped out for a new one in addition to all the fixes last year. It ran fine with no whining until the last (warmer) ride.
2) It is now audibly whining pretty bad. No codes yet, but I was having a low boost problem to begin with. Now that I've remedied the boost problem, I'm worried I'm going to run into fuel pump problems. The sled unfortunately just lost its warranty.

Polaris is out of the fuel pump to begin with. Has anyone actually figured out how to really fix the whine? Or is it something to not worry about until you see codes? Its pretty loud. TIA!

My buddies new 24 boost has the same whine.

At this point I’d say it is normal.

What was causing your low boost issue Jeff?

I’ve yet to see the fuel pump whine issue.

I’ve yet to see the fuel pump whine issue.

Actuator rod worn + very small leak at throttle body adapter (not confirmed, but after disassembly one of the rubber flanges was partially broken which could create a very tiny leak)

Mine started to whine a bit too. Next ride I’m going to toss a cup of oil in the fuel tank to see if that will lube the pump enough to stop the whine. Maybe make it last a bit longer too.

My sleds doing the exact same thing. I know when i put one of those buick filters in last year. The wine stopped. Of course the dealer put the updated sock in. I bet the filters are plugging up

I ride in the flatland world primarily, but we've found that excessively noisy fuel pumps are often traced to the in-tank fuel pick up filter being plugged. I've had it happen on one of my sleds also. After riding for a few hours, it would be loud enough to hear with the sled idling and me wearing earplugs. I changed the pickup filter and everything was back to normal. It also seems as though filters in certain years have a greater tendency to plug than others - maybe the micron rating was smaller? Also, ignoring the issue will eventually kill the fuel pump, so best to get it taken care of.

My 23 boost started whining for the first time last weekend on and off intermittently. Ambient temps were really warm in alpine all weekend. I’m thinking it’s the exchanger heat soaking the pump and causing the issue

Change filter before pump craps out

i'm going to pick up a filter today. Any tips on changing it?

Take your time when pulling it out so you don’t damage the float it’s pretty easy and don’t forget there are alignment marks when you reinstall it

 

[d8grandpa]

They are sold in a kit and there is 2filters in the tank

yep. picked up the kit. got it done. those filters are kind of a PITA to get off the retainers.

I don’t have pics I believe there is an arrow on top to get the correct orientation of the assembly in the tank. It’s been a couple years since I’ve done one. Maybe someone can chime in or show pics.

From the first photo you can’t really see it, from the second when zoomed in there are two lines on the pump housing just inside of the retainer nut. The aren’t very obvious, kind of look like they were scratched on there with a pick. This is my 22 boost I took apart back in Feb of 22. You can see mine was not quite lined up from factory.
