So, I've noticed a trend, my sleds fuel pump is whining at high elevation, but not at low elevation(900ft vs 10k+). It's not repeatable by my dealer at low elevation, and my sleds not throwing any codes. This is my last season of warranty, so I'm trying to get everything fixed. Any thought's?
Fuel pump whine only at high elevation? 23 boost

At high elevation, does it whine at idle, or at what throttle point does it start?
It was whining at idle yesterday, today it's not doing anything. Hard to hear it at higher rpm.
Buddy just had his fuel pump replaced on his 23. He hasn't had that many good days on that sled
Well, i did notice a slight whine at idle earlier. Nothing pronounced when riding the sled, only at idle.
Any ideas?
My 22 boost never whines in the morning but it will start to whine after running a couple hours. The next day it’s quiet again for the first couple hours. I don’t really ever run mine at low elevation aside from loading up. I wonder if it’s the gap in run time that it quits whining. When my sled was new before the pump was replaced it whined so loud you could hear it 200 feet away. I had low fuel pressure codes with that pump.
Just annoying i cant recreate the issue here at home. If I could, id have something to stand on with my dealer for warranty.
If this common issue is present on your sled, get the tank down to a couple gallons of gas, warm the engine up to 120F and see what happens in the parking lot. Might need some time with the warmth (a few cycles, let's say) for the cooler to really warm up your fuel. Just an idea.
