How are your fuel lines in the tank??

[sledneck_03]

no way, we have been using stabil in everything we own for years, dump some in run it turn off fuel and let it die and it sits till next season......

and i have pulled the fuel valve off a couple of the bikes/quads that were up to 15 years old and they used the ****ty yellow hose for the open and reserve pick ups and they never needed replacing.

I wouldn't have thought so either. Just my luck I got some bad lines from the factory maybe??! I did notice not all the fuel lines were of the yellow tubing, there is about 6 inches of black line from the pump to the first pickup. It is still in good shape, no cracks or signs of wear. Wonder why the difference?

because whatever killed the rest of the line wasnt high enough to get that part of the line(IE it was low on fuel)....

I dont use stabil, I use a product called seafoam, been using it for over 25 yrs..by far the best fuel product you can buy..period, cleans fuel system, disperses water, and stabilizes fuel for 2 yrs...I highly recommend it for all internal combustion engines....

Well, I would agree to that but I always store my sleds full of gas, then in the fall siphon it out and put in fresh gas before starting. (Mt wife's car gets the old gas, it's only a Honda.) I've seen seafoam in the parts stores, heard good things about it. I'll have to try it out.

The black rubber line sits on the bottom of the tank as well...

This one is just plain strange...Those lines are translucent violet color when new... I wonder what the heck happened...

I'm leaning towards some type of additive.

Pry off a couple of the crimped-on hose clamps... I'm interested in seeing what the hose looks like under them.

MH, the lines are purple when new but they turn the yellow color very very quickly. I got a new fuel pump assy last year and got to see it first hand.

Sea Foam Is GREAT..

If any one need it ... PM me.

thanks matt

I took the hoses off at the rest of the connections, didn't have to pry the clamps off as the hoses broke off from under the clamps. The rubber under the clamps were rotten. But away from the ends the hoses were good, you could stretch, twist, and bend them. They would not crack or break. I'm trying to remember what the canister is that Polaris installed in the fuel line after I bought it which was a recall item. That is where the lines also came off after I found it laying in the bottom of the tank.
Got a new pump coming from Ebay that I found, exact same part number. A lot cheaper then through Polaris. It is the complete assembly.
My son is taking a piece of hose with him to school (Chico state) to one of his teachers, that want to look at it. My son is also studying mechanical engineering so maybe they can figure out what happened.

My fuel lines looked just like yours on my 06 900. The ends weren't rotten yet but the lines were real yellow and chalky. Tiny bits of plastic would collect together when I tried to see if the chalky stuff could be wiped off. The black hose was still good so I replaced everything with black fuel injection hose from Oriely auto parts.

I pulled eveything out because my 900 would bog when below a half tank of fuel. The little black plastic piece the fuel line connects to on the pump was loose and needed to be re-glued also.

Hey AK..I saw that commercial for SeaFoam..isnt that the denture adhesive? Seabond seafoam all the same! :>))))

The interesting thing I saw in re to this post was the combination of ethonol and Sta-bil and de-icer. What deicer was used? There are some that are not good for the two stroke motor.

I dont know if it was related but interesting. I had small red pieces of a material that looked like plastic that clogged the T piece between the tw carbs. I and the shop both went thru everything and it was that little 5cent part that was over looked so many times. I had picked up a huge amount of water from a brand X gas station (on the way to Mt Baker) I too ran the deicer..now I used the Polaris deicer in the skidoo so who knows what that could do. Whatever it was was able to get past my fuel filter. The pieces were too large to do that so they may have been created and accumulated over time.

The best luck I have had is to use a 50% race mix in the off season..start the sled up every three weeks (keeps the neighbors happy too) before the season starts I siphon and put it in the truck.

Also had an additive that i used many years ago as it worked awesomeit was called rocket fuel, it would soften rubber. Use chemicals in combination and all bets are off I would think.

Another good topic that ties in with the "crappy gas" thread..

TTT Good Stuff in here!!

I know of a 2008 600 CFI that has the same issue.

What is the distance between the two suction intakes? Or is it super critical that they are spaced back to the factory distance?

 

[mtnsledder]

Thats exactly what the fuel lines on my 08 D8 looked like a year ago when I had the tank off and heard something rolling around in the tank. It turned out to be the in tank fuel filter was no longer attached to anything and all the fuel lines were cracked like yours.

Definately flush all the residue out of the tank and replace the external fuel filter.

 

[73 Starfire]

Here are some pics of my 08 600 CFI referenced by Volcano Buster above. In the first pic there is what appears to be a filter(?) with a third port with an orange rubber duckbill flapper that just happens to be the same size as the external filter that you would normally replace as per the maintenance recommendations. Is this a filter or does it serve another purpose? If it is a filter, does anyone know where a new one might be obtained as Poo only sells the complete fuel pump and pickup as an assembly.

My pickup hoses have completely fallen apart and disintegrated. The black rubber hose at the bottom of the pump seems to have not been harmed. I have added Sta-Bil in the summer as the only additive. I have been running 10% ethanol fuel as non-ethanol is difficult to find here.
