Fuel pick up problem

Working on a 99 Polaris XCR800. Cleaned the carbs Got it running on the remote bottle. Runs good. It has about 2" of fuel in the tank. I put vacuum to the fuel fitting on the tank and can't draw anything out out. Is it just not enough fuel or should I replace the pick up line? Are they weighted?

There is a weighted filter on the pickup line. The pickup line also fails from time to time, usually at the internal nipple on the fitting. The line comes out through the fitting on the tank. If you do get cracks in the pickup line, you will have limited range as you can't get the fuel below where the crack is. You can test the line by fishing the internal line out of the tank fill, removing the filter, and capping it. Then hook your vacuum up to it and see if it will hold a vacuum. If not, you have a crack in the line. You could do the same by pressurizing it as well; I use a syringe filled with gas, if I can squirt gas without building up any pressure into the line, the internal hose is bad.

fuel pick up problem

Thanks for the replies. Haven't worked on sleds for years but I retired from government work and now work at a repair shop part time.
Got this feeling I'll be seeing this sled again. When the owner picked it up he told us he drowned it last year. Which explanes the soggy seat and water in the tail light reflectors.
