flow problems

[spikehs]

I have my plumbing all hooked up and the tank full of water, but I am getting virtually no flow from the outlets to the tank, if I put my hand over it I can barely feel the flow at all, the pump is a mag 250, so I figured I'd be able to feel/see the flow a bit. I was thinking I might have to many 90deg bends, but I really can't see them reducing the flow that much. Anyways here is a picture of the plumbing:

the long tube comming over the back is the intake, then its plumbed into the 2 returns which then split into 4 (see second pic)



in the 2nd pic you can see i popped off the tube to see what the flow was like there, I coud still barely feel it.


might the pump be faulty? The only other thing I can think of is that the intake is somehow restricting the flow to much, otherwise I am kinda stumped. Any help would be appreciated. thanks.
