Hot fuel cheap pump gas = problems
Matryx boost fuel pump

My sled had a fuel pump whine yesterday. It was low on fuel and I lawn darted it of a cliff, it landed upside down and then started whining.
So the problem is obviously that the pickup doesn't follow the fuel in the tank. So any time the sled is upside down the pickup is possibly sucking air, and the fuel pumps do not like to run dry

Well, add me to the list! 136 miles and low fuel pressure warning with loud pump has started. I can shut it down and get it to reset, but as soon as I get on the throttle it goes back into warning mode. Hopefully my dealer can get this addressed quickly.
agree as does my dealer, so very curious to see your temp experiment results. Dealer ran bulletin last week on mine and everything was to spec and they said Polaris is still telling everyone it is from air getting in system that needs to clear (so just keep running it).
Mine threw code P0196 (Fuel Rail Pressure Sensor "pressure too low - moderately severe) again yesterday, 30 miles in at about 55-60% tank when it was running a bit warmer. Did a big snowboard shuttle lap on other sleds and let it sit for an hour. It was cold cold when I fired it back up and I had full power/no codes ripping 10+ miles back to truck
Unfortunately I think problem will persist until Polaris releases fully revamped fuel pump...
Could sorting out the fuel pump be part of the delay in shipping out the remaining snow checked sleds?
Make one wonder............

I heard rumor that the ones that show up later this week won't whine
Spill the Beans what did you hear lol
My N/A Khaos started the same way and started throwing codes on the third time out .

My NA Matryx sled pump was wining and I couldn't go over 6500RPM without going into limp of low fuel Pressure. I disconnected my pump suction from the black box in the fuel tank and ran a separate suction line. Sled is now running with full power and no more pump wine. If you look at a Axys fuel system this is basically how it is setup. At least I can ride now waiting on Polaris for a fix.
Got any photos of this minor surgery, parts list? diameter or hose etc?

I didn't take any pictures. I disconnected the stock fuel line right at the inlet of the pump and added about 12" of 3/8 fuel line and a new suction strainer. Everything is still in the tank and the level indicator is still working. This is a picture of the Axys system. Basically have it setup the same way.
Did you use a new stock matryx strainer or ? Thx for the info
Are you saying separating the return and supply fixed this?
Holley HydraMat would be a very good thing then!

'22 Slash with 400 miles. Fuel pump started whining at about 250 miles but no codes yet.
As a few people stated above, likely not a heat issue. I boil gas in fuel injected dirt bikes several times a season and never had an issue with heat failures. What's usually the issue is the cheap Chinese parts used to build them.
