In my discussions with Bosch, they ask for a MINIMUM of 1/2" line on the suction side of that pump. Using it with the stock selector valve isn't recommended if you follow their specs...as it will make the pump work harder and may prematurely kill the pump.
I'm not aware of a pump that is small enough to pull through the selector valve without the restriction putting too much stress on it and still large enough for performance injectors...and that's rated for diesel fuel and reliable. That's a pretty tall order.

plum 2 selector vales in parallel.. i used the nominal measurement as the ID
3/8" line (stock) = .4415 in^2........x2........ .8831in^2
1/2" line = .785in^2
5/8" line = 1.22in^2
so 2 3/8" lines outflow a 1/2, but not a 5/8

Agreed.
We use 5/8" pick up in tank, -10 lines to filter, then -10 lines to inlet of 044. No less if you want a reliable system.
