No to low wiper pump pressure

[Teambanzai]

I have a 2000 Montana with 187,000. I baby the thing and for the most part I get good service from it. I do have one problem that is driving me bonkers. The fluid to the front wipers has caused me all sorts of problems recently. The old wiper pump went out so I got a new one from Rock Auto, well it works, but there doesn't seem to be enough pressure to get the fluid to the wipers. I have pulled all the hoses and blown pressure through them and they are all clear. I have blown air back through the pump and it passes through easily. The pump motor is working. Could it be that the pump is just too weak? When I disconnect the hose and then turn on the activator it only pumps the fluid out and inch or so in the air, should it be shooting it out very forcefully?

Thanks for the advice.
