Polaris fuel line help

[JakeVIII]

I have a 2002 Trail Touring I'm rebuilding.

I have two part numbers for fuel line:
8450117-250
8450040-600

8450040-600 is 1/4" internal diameter. But I can't figure out what the internal diameter for 8450117-250 is supposed to be.
Do you know what it is?

Buying the stock stuff is sort of out of the question: $96.99 plus $64.99 = $161.98 for over a metre of fuel line is a no-go for me.
Can you also recommend some reputable aftermarket fuel line brands?

No idea about size of the other line but any after market fuel line you buy is generally good for 2yrs or less. sometimes the price is worth it in the end

That actually helps a lot. There's such a huge price difference it was hard to tell if it's the dealer trying to get you, or if everything else is not so good.

Dont forget to change the pick up line in the tank and clean the filter in the tank

Other size is 1/8 inch for the fuel vent line.

Used to buy Tygon tubing for the fuel pick up from a marine repair facility. Designed to withstand the decomposing effects of poor fuel additives.

Does anyone have a fuel line diagram for this kind of machine? 550 with two Mikuni carbs. I have a fuel line going to the pto side carb from the tank and a fuel line going to the mag side carb from the fuel pump. It feels like that may not be right, but it's how the sled was when I got it.
