I tried to look for diagrams on All Data but none for the washer fluid lines. It's been a while since I worked on that system. I don't remember any check valve in the fluid line but it makes sense that there would be one. The most common problem I see with the pump is the electrical connections where the pump plugs into the wiper motor. Are yours getting hot? This is a sign of poor connection. I also see the lines, especially the spray nozzles themselves, become glogged with residue from the soap in the fluid.

As far as routing the lines, the suction line goes straight from the bottle to the pump. It may have check valve in it. The lines from the pump t-off to the nozzles. Pretty straight forward. If the pump isn't spraying fluid from the nozzles, first make sure the pump is running, then look for a restriction in the suction line by disconnecting the outlet and running the pump to look for flow from the outlet. If no flow, look for a restriction in the suction line. If there is a check valve, it seems like that would be a good place for soap residue to form a glog.

There is no vacuum in the washer system. If there is any connection to intake vacuum, something is not connected properly.
