What year? Carbed sleds would have an impulse line off the engine, EFI's are electric pumps.

I think the impulse line is heavier black hose. The fuel pumps can be taken apart and rebuilt. It's not all that normal for them to leak. Is the fuel coming from the black hose? Is the crankcase full of fuel? Can you tell where the leak is? Maybe it's just the fuel lines?
