On a 2 piece fuel rail, the last cylinder to recieve fuel is #1, correct?

I'm having issues with the cylinders getting progressively leaner as they go #4-richest #1-leanest. Something is screwy, and I wanted to verify this as I make a plan of action to find the problem.

I'm not running some wild high HP setup, just 14 psi. I beleive there something wrong in the pump or lines. Already swapped a different filter in. Just waiting to find a long enough hose for the FP gauge so I can tape it to the windshield on a test drive.
