If you replaced any of the hoses with cheapy aftermarket versions you may have gotten a version that isn't stiff enough. Or you may need to find one that has a spring inside to prevent them from sucking closed.

I bet 100 bucks you have air in the system. let the vehicle run and keep squeezing the top hose. Start it when its cold with the cap off so you can refill the level as it drops. Do this untill the vehicle reaches full operating temp.
