Anyone else have fuel pickup issues going down hill. Any thoughts to why? It really hasn't been a problem until my last couple of rides but its getting worse now. It doesnt happen all the time and seems to be worse if i stop and shut it off pointed down a decent slope then start it up and go again. It will just cough and sputter until i get to flat ground for a second and then be fine. Snopro 800 about 650-700 miles
Fuel pick up issues going downhill?

My sled just started having a similar problem, except it is on hard pulls(climbing). It boggs out, like it is running out of fuel. One time I had to get it level to get it started....???????
I'm going to take hood off and check vent lines, etc...

The up hill thing makes sense because of the tank design, if you're low on fuel atleast, I actually ran out of gas the other day on mine.

I bet the uphill bogs are from snow ingestion in the intake water in the Nose making it to the throttle bodies

Had a buddy that had problems. Not sure if they fixed it yet. Start running out of gas about 6 - 7 gallons down. I noticed mine when I was real low, running back down trail to lodge, every corner when I hit it the throttle it would bog slightly then come out of it.

Same thing here...ran out a couple times going up hill. Fuel light is on and the crappy little gauge shows empty. Go to fill it up and it's 6 gallons and it's full. WTF!

sounds like the pickups are falling off or something???
It's a fuel pickup issue. It has been discussed in several treads in here since beginning of the season.
Cat has a service bullentin how to fix it if it occurs. Have to pull out fuel pick up assembly, split them, and drill a small hole in the one membran that not has a hole in it.

Or ask that darn Dam Dave guy for a flare and they will come to your motel room.

mine started doing this last ride as well, each time going up hill, gauge was reading "fuel" but i knew it had at least 3 gallons in the tank still, kept doing it for a bit, then all of a sudden it flashed "octane" on the way back to the truck..wtf?
i put about 9 gallons of fuel in it so it was low but still when it was cutting out on the hill it was an hour earlier so i knew it still had plenty of fuel to get back to truck, very frustrating!
whats the fix on the thingy (smart valve) the other dude mentioned???

Could you send me that sheet? I would rather fix it myself....

Hmmm. There may be more than one problem out there causing this issue then.
That was not my issue but one step at a time.

what was your issue?
I dont like having my "cat" being the "problem sled" of the group.
Usually "that" sled doesnt have an Arctic, or a Cat in its name........just say'n...

Same crap at half a tank but mine would completely run out of fuel in a long climb even with 3/4 of a tank. Always restarted up for me after about 20 pulls and being level.
Read about a fix the turbos were doing after adding boost. It had you put in a T before the front smart valve and swap the front valve with the rear vented valve.
No probs since right down to 3 liters left (whew, note to self, bigger tank next year).

So how the heck do you get inside the tank to get at this "smart valve"?
G
Through the fuel pump access.

Not trying to stir the pot here. I was under the assumption that Cat and Poo used the same "smart" valve pickup system. The screen that is in the bottom is supposed to filter out any water that is in the tank and keep it from being picked up into the motor. Also, I had mine out about a month ago. Quite simple, I'm not sure how they would have been installed/assembled wrong.
