No static restriction. No apparent dynamic restriction.
Left or right, it does not discriminate.
Output fuel line had a Y that fed carb and return, while blocking the other port at the pump. I put a new pump on and re-routed pickup in, return out, carb out.
The pickup tube was hardened and would not come off either end. I just now put the one from the Honda on it (replace with known good) and will test at an autocross on Sunday.
Thanks for all the replys.
