Well one is the supply and is under presure (be carefull) the other is just a return. As RJ asked does it run? Why are you into it?
Assuming it doesn't run the pump will only supply presure when you pull it over fast enough, and on a inline gauge it should be 30-35# and hold. If not you could have a blown fuse, a bab smart valve (water soaked) or bad pump?
Good luck and keep us posted

Yes it runs only if i put fuel directly in the cylnders, do you know where i can check for the fuse? no fuel comes out of the line even when disconnected and turned over. i ran like a swiss watch last year for the whole 100 miles i put on it and started as reciently as August when i did a pre season check. then i tried to get it to go a few weeks ago and no go. i appreciate the help!!!!

Did you get an owners manual? The smart valves are in the tank. Once your sure it's the pump, take the cowling off and the bars(makes this easyer) there is a rectangular plate, the pump and valve all come out , be carefull and take your time getting that unit out. But likely it isn't the pump, Check your wireing and switches first. You do get spark right?

I jumped the 12 volts across and got a small thump but no fuel is this the pump then or would i get no noise with a bad pump? can anyone tell me more about the smart valves and would they cause this? where would the fuse be?

The smart valves are the screen pickups (16 and 27 below in pic) in the tank mounted to the fuel pump that stops the pump from draining back.
I have seen them stick and stop the fuel flow.

1998 and 99 pumps are square and held in with screws.
2000 and newer pumps are round and held in with a hollow
threaded ring like a gas cap.
Pull it apart and spray the valves with carb cleaner and take a screwdriver handle and tap on them lightly, spray and tap several times.

If the valves are "gunked" closed,the pump will not run.

take and run the pump with a 12 volt DC power source and keep tapping the valves and it should take off.
Once you get the pump to spin, put it back in the tank
and hook all your lines back up and use the power source
to "prime" the pump. After it starts to load, hook the wiring back up and the sled should start and run.

The 99 or 98 I worked on the fuse was in a holder just above the chain case. ( 5 amp ) ?
I had the fuel pump out of a 95 Pantara and it had I think 4 wires (fuel gauge) Yours should have just two you can put 12v to it and see if you get an out put, if you do then it could be maybe a stator? Or a bad ground? Good luck!

I have never seen a fuse in a batteryless efi sled, The older battery type were fused.
The is one fuse in a holder that is a 7.5 amp by the chaincase, but it is for the solenoid on the electric start.

If it has electric start is the battery dead? or low? Start there, Not sure on 2000 but the older ones if it has a batery it may need a full charge to activate the pump. Before all this started when you turned the key on and the kill switch was on did you hear the pump cycle?
