I was thinking could one just extend the carb heater line to go arround the fule pump before the carbs.
just an idea als thoght of making a little aluminum .250 think by 3"x3" tank to fit under the fuel pump to heat it.


Or how about just taking a heated hand grip and installing it under the pump, Ive seen ones for sale that are just the internals. I suppose you could just splice into your original heated grips and install a switch. just some other ideas.

what do you guys think
 
thats what ive herd but i thought i saw somewhere were someone did the mod and still it froze, thoght having a heated grip under there with the washers would come in handy especially if you have it wirred to a heated shield style conection, then if it freezzes your buddy could pull up beside you and plug into his sled and a couple mins later your defrosted.


Just thought it would be an extra saftey net.
 
Routing the carb heater around it would do nothing because it is when the sled is sitting for awhile that it will freeze up and be hard to get started again. Just shim it up off the tunnel and it will be fine
 
I live in the great white north of northern ont. T.bay area , and have never had mine freeze.
 
I have shimmed it up. But just was laying in bed and thought of some ideas, thought the heated grip swould be something extra.
 
In order to freeze it first has to have a substance in liquid form touching the vent. The chassis gets warm enough to melt snow in that area, and with the vent laying right on the chassis, it can set in the resulting water and then freeze as it sets. The key is to simply keep it away from liquid (melted) substances that can subsequently freeze. Adding another heat source would likely simply result in more liquid (melted) substance in that area. Keeping the vent up off the chassis works well unless you get a "flood" in there high enough to touch the vent while setting and cooling down. This might happen if you pressure washed the engine and then sat the sled outside in cold weather to dry (freeze), or if you filled the engine compartment with snow that then melted and refroze quickly. Plugging the vent also works unless you are modded enough to really need a lot of fuel. In this case you should likely upgrade the fuel pump anyway.

Water in the fuel will rarely get to the fuel pump unless the tank contains gas above the point at which water freezes, and then the sled sets in freezing temps. Not very likely to happen as water in the fuel tank is usually little frozen ice balls when the air temp is cold enough to freeze water.

Hmm, when I'm laying in bed and start thinking of something. I usually get a slap from the misses...LoL

spin the chamber and cross your fingers. it takes about 15min to do the update and 20min with a hair dryer if you can find one when it does freeze.
i would fix it now and concider yourself lucky.
