What's that tank plumbed in tho? all 1" and don't you have loclines? Those pumps are flow pumps not really the best choice for pressure situations...

[The Grizz]

Ya it's 1" out of the pump, then split into 1" but then goes down to 3/4" to 4 loc-lines.

So what I want to do above do you think it would work? I really want to be able to have some SPS in it.

I'm not sure man. I'm a big fan of running closed loops on dedicated pumps. Not that I *have* before but I'd run lower flow through my return (and manifold off it) but with a seperate pump. Hammerhead to do the 4-way on it's own...

I have a closed loop now in the 165 & don't like it as it has caused me more grief then it's worth.

running it off your return means you need to deal with whatever flow you want out of the 4-way as a bare minimum through the sump too.
